Also where did you get the 10 million operation, and decrypting a cipher is not one operation but a set of operations. Numerous tools are available to decode the data without the need for any key. Convert a hexadecimaly encoded text into an decoded string or download as a file using this free online hex to text decoder utility. We can use Advanced Encryption Standard (AES), a form of symmetric encryption, to securely store our secret data. Calculate hash of file or text. This class provides class functions to perform data encryption, Base64 encoding, hashing, and generation of message authentication codes. To compute a one-way hash value, SHA-256 uses a message schedule of sixty-four 32-bit words, eight 32-bit working variables, and produces a hash value of eight 32-bit words. Typically, it is expressed as a hex number that is 32 digits long. Requirements for a hash function. SARC-63Y - Online encode binary data in PowerScript. For MD5, l = 512, and s = 128. This site is not directly affiliated with DVDVideoSoft. Similarly, symmetric encryption uses a single key to encrypt and decrypt data. At the same time, a 128-bit hash function RIPEMD-128 that has a four-round compression function was proposed to replace RIPEMD. 32 hashMerkleRoot 256-bit hash based on all of the transactions in the block A transaction is accepted 32 Time Current block timestamp as seconds since 1970-01-01T00:00 UTC Every few seconds 4 Bits Current target in compact format The difficulty is adjusted 4 Nonce 32-bit number (starts at 0) A hash is tried (increments) 4. Add to compare The actual product may differ from. Hash functions are used in computers and cryptography. It happens at the "examine game data" step. The problem with what you linked to is that, because of collisions, you cannot guarantee that the text that technique comes up with is the only string that generated that hash. It's a cryptographic hash. Source Code. While the hash function is to get blocks of data and return them with a fixed-size bit string or hash value. For password storage, it's not enough to just encrypt/decrypt. In this case Pl3m5Y95 is the salt and t3Nk4zEXTCXDP4Vs4cL0p0 is the hash. Add to compare The actual product may differ from. – The secret key is known only to the sender and receiver. For example, when transmitting encrypted data, symmetric encryption algorithms use the same key to encrypt and decrypt data at both ends of the transmission media. By default these functions implement AES with a 128-bit key length. That’s because this task doesn’t make any sense. Hash values, hash codes and hash sums are returned by functions during hashing. The secure hash algorithm originally started out as SHA0 (a 160-bit hash published in 1993). What can you do with Online Decrypt Tool? This is very unique code decrypter tool which helps to decrypt data with different encryption algorithms. Adler-32 is often mistaken for a CRC, but it is not, it is a checksum. SPECK Parameters. This site is not directly affiliated with Encryption And Decryption. I assumed that I would get a option to choose 64 bit, but did not. a hash function for 32 and 64 bit pointers Hi Guys, I understand that a good hash function is hard to find, but this problem seems to get event more complicated when i tried to find a nice, efficient way to hash pointers. Still, you cannot assume it as one of the most secure VPN encryption because Blowfish works faster than 3DES encryption. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. NET and C++ provide different implementation to achieve this kind of encryption. Which hashing algorithm is best for uniqueness and speed? Example (good) uses include hash dictionaries. Encryption key length trends towards a "bigger is better" perspective: the longer the key, the better the encryption. 64 bit architecture The 32 bit hash isn’t too important for large amount of data matching, so I only worked with and tested the 128 bit version. To help put the numbers in perspective, I've included a few real-world probabilities scraped from the web, like the odds of winning the lottery. Each bit or character from the plaintext is encrypted by a modular addition with a bit. taking as input any message M. digestIT 2004 is a Windows Explorer context menu that calculates the MD5 or SHA-1 hash of a file or files. 32-bit hash-small JavaScript performance comparison. It bypasses the DVD copy encryption or protection set on the DVD to prevent illegal cloning or copying. MD5, SHA1, SHA256, SHA512 and more. SHA-1, SHA-2, SHA-256, SHA-384 - What does it all mean!! If you have heard about "SHA" in its many forms, but are not totally sure what it's an acronym for or why it's important, we're going to try to shine a little bit of light on that here today. MD5 was designed by Ron Rivest in 1991 to replace an earlier hash function, MD4. Typically, it is expressed as a hex number that is 32 digits long. Tool to decrypt / encrypt with hash functions (MD5, SHA1, SHA256, bcrypt, etc. MD5 is a one-way hash function which creates a 128-bit hash value, and is most commonly used in digital signature applications. Let's hash it out. There is a human factor in the security of encryption. This represents binary data in an ASCII strong format. Get-Bytes(32) method to return the 32-byte value of the key. For examples: Samples are taken from a sentence "The World is wonderful" if it is represented into byte it would be "87 111 114 108 100 32 105 115 32 119 111 110 100 101 114 102 117 108 108 "(19 Byte without the quotes). In early 2017, a new variant of CryptoMix, called CryptoShield emerged. The hash values are indexed so that it is possible to quickly search the database for a given hash. But this is difficult to achieve, and you should not assume (for example) running the same algorithm twice with different initial states will produce uncorrelated. crack hash, crack hash with salt, crack hash md5, crack hash with john the ripper, crack hash with salt, crack hash md5, crack hashdump, crack hash code, password cracking, crack hashes online. The AES encryption algorithm encrypts and decrypts data in blocks of 128 bits. A hash algorithm is basically a one-way encryption that outputs a fixed length. One might reasonable choose RC5-32/16/7 as such a replace- ment. * * This version uses native 32 bit registers, so it needs a 386 or 486 CPU. Performance impact of slower encryption/hash/group settings in Phase 1. Encryption algorithms are commonly used in computer communications, including FTP transfers. Get-Bytes(32) method to return the 32-byte value of the key. Even a slight change in an input string should cause the hash value to change drastically. For instance, a function that creates a 256-bit hash (like SHA) will have fewer collisions than one that produces a 128-bit hash (like MD5) because there are more possible hash values when you have more bits. I am trying to set up WEP 128 bit encryption for my wireless network using the Windows Wireless Configuration Utility. Taking that further, one byte or eight bits are represented by two hex digits, e. This site allows you to encrypt or decrypt any md5 hash, we have our own database with more than 10 million keys, also we look for your hash on 23+ others web sites. Hashes are often used to store passwords securely in a database. SHA-1 produces a 160-bit (20-byte) hash value. With hash toolkit you could find the original password for a hash. We represent a tuple (X a; ;X b) by X[a b], when the X i’s are bit strings, we also identify the tuple as the concatenation X. For example: Unit testing, C# 2. AES-128 bit encryption is much secure and faster than Blowfish and 3DES encryptions. GitHub Gist: instantly share code, notes, and snippets. It was designed to replace MD4. When the string reaches to its destination a same formula applied the string to decrypt it. 1 to 64-bit Windows 10. Similarly, symmetric encryption uses a single key to encrypt and decrypt data. Hash functions are used in computers and cryptography. What can you do with Online Decrypt Tool? This is very unique code decrypter tool which helps to decrypt data with different encryption algorithms. Some doll sized hangers are included. MD5 uses multiples of 512 bits as input and produces a 128-bit message digest (or the hash) as output. it uses a key to encrypt data and then uses a different key for decryption. Then encrypt the drive by BitLocker (see above). 128-bit encryption still good enough against GPU brute force attacks? 128-bit encryption You may have notice that we are already aware of the GPU-based hash. This is the new and improved version of md5 engine. As with any encryption process, it relies on keys. Please do not use 40 bit keys to encrypt your sensitive data. Common encryption algorithms and code recognition 128位(16字节)的散列值(hash value break chunk into sixteen 32-bit little-endian words w[i], 0. It's a cryptographic hash. The mcrypt function will be deprecated feature in PHP 7. But they are slower than various non-cryptographic hash functions, as these functions are primarily designed for security, not speed. Rijndael uses 8-bit S-boxes as its source of nonlinearity and simple XOR (exclusive-or) operations (it does not need addition). hashcalc hash checksum algorithm md5 sha1 sha2 crc32 verify calculate hash message digest checksum crc hmac algorithm file data sum authentication key password encryption encrypt 128 bit check vista freeware, shareware, software download - Best Free Vista Downloads - Free Vista software download - freeware, shareware and trialware downloads.

The created records are about 90 trillion, occupying more than 500 TB of hard disk. Read, How to provide USB Disk Security, How to Secure USB Storage. EncryptedRegView cannot decrypt the data because it needs to access system keys. Simply, we need all these 3 fields - Salt, EncryptedVerifier and EncryptedVerifierHash to generate a final decrypted hash value which then will be compared against each key in the key space (brute forcing). This tool uses the mcrypt_encrypt() function in PHP, so for more infos about the parameters used check the manual. SHA1 vs SHA256. I spent a little bit of time last night and this morning trying to find some examples for AES encryption using Python and PyCrypto. Well done! For the hash function to have the correct properties, it is assumed that CHAR_BIT is 8 and computations use 2s complement arithmetic. SHA-256 : uses 32-bit words. DCPCrypt is hosted in a Git repository. pbkdf2_hmac (hash_name, password, salt, BLAKE2s, optimized for 8- to 32-bit platforms and produces digests of any size between 1 and 32 bytes. Calculate hash of file or text. Supported hashes for decryption: Usually it's not possible to decrypt a hash, but with. In addition, a 128-bit value is no longer secure enough as described above, and thus RIPEMD was improved to the 160-bit hash function RIPEMD-160 in 1996, which has a five-round compression function ,. AxCrypt on 32-bit and 64-bit PCs. Windows 32-bit, EXE Installer, VSFileEncrypt_Setup_x86. Interesting fact, 128-bit encryption is considered to be logically unbreakable, so you could say. SHA-224 Description SHA-224 may be used to compute a one-way hash value on a message whose length less than 2^64 bits. As far as I can see by browsin is that this is not possible and the only way to this is to encrypt and compare hashes. Performance impact of slower encryption/hash/group settings in Phase 1. I will encrypt this file using AES-128 and encryption mode, ECB, CBC, CFB, and OFB respectively. This paper proposes DeWrite, a line-level write reduction technique to enhance the endurance and performance of secure NVMM. While this will make current rainbow tables useless (if the salt is properly chosen), if the salt is hard-coded into a popular product that salt can be extracted and a new rainbow table can be generated using that salt. Even my 10 year old laptop, running an inefficient Perl script like the one above, should be able to do it in a few hours; with a faster computer and a more efficient script, it should be doable in minutes. /file - Decrypt an encrypted file /dir - Decrypt all the ". SHA256 (Secure Hash Algorithm) is a cryptographic hash function designed by the National Security Agency (NSA). The method of claim 11, wherein the hash function is selected from a group comprising: a Message Digest 5 (MD5) algorithm, a 16-bit cyclic redundancy check (CRC), a 32-bit CRC, a 64-bit CRC, a Secure Hash Algorithm (SHA) Version 1, a SHA Version 2, and SHA 512. A hash (SHA 256) is used to protect the encryption key. For examples: Samples are taken from a sentence "The World is wonderful" if it is represented into byte it would be "87 111 114 108 100 32 105 115 32 119 111 110 100 101 114 102 117 108 108 "(19 Byte without the quotes).

What is AES encryption? It is a webtool to encrypt and decrypt text using AES encryption algorithm. The padding is similar that used in MD4 and MD5, but instead of the string length stored in bits as 64-bit integer, only the string length as a 32-bit integer is stored. The iterating method is usually called the Merkle-Damgard meta-method (see [6], [16]). Pci Encryption Or Decryption Controller Driver for Windows 7 32 bit, Windows 7 64 bit, Windows 10, 8, XP. AES_ENCRYPT() and AES_DECRYPT() implement encryption and decryption of data using the official AES (Advanced Encryption Standard) algorithm, previously known as “ Rijndael. As you may know, DVDDecrypter. With the aim of developing the secure and safest website you can, our password encryption utility is an absolute necessary. It got too big for me. To help put the numbers in perspective, I’ve included a few real-world probabilities scraped from the web, like the odds of winning the lottery. As far as I can see by browsin is that this is not possible and the only way to this is to encrypt and compare hashes. This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. In addition, a 128-bit value is no longer secure enough as described above, and thus RIPEMD was improved to the 160-bit hash function RIPEMD-160 in 1996, which has a five-round compression function ,. arrangement used for encryption and decryption, both determine the type of cipher it is. A fixed salt is when a programmer uses the same salt for every hashed password. Online Reverse Hash Lookup tries to reveal the original plaintext messages from specified hash values of several cryptographic hash functions. There are a few scratches on the outside and a bit of wear and tear inside and out but as you can see from the photos, it shows really well. Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed "hash" (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. Examples of Symmetric algorithms (Symmetric-key algorithms). This example will automatically pad and unpad the key to size. You can make a contribution by modifying the price below. Hashes are often used to store passwords securely in a database. 32 hashMerkleRoot 256-bit hash based on all of the transactions in the block A transaction is accepted 32 Time Current block timestamp as seconds since 1970-01-01T00:00 UTC Every few seconds 4 Bits Current target in compact format The difficulty is adjusted 4 Nonce 32-bit number (starts at 0) A hash is tried (increments) 4. The HASH function included with DBMS_CRYPTO, is a one-way hash function that you can use to generate a hash value from either RAW or LOB data. With hash toolkit you could find the original password for a hash. Symmetric ciphers use the same (or very similar from the algorithmic point of view) keys for both encryption and decryption of a message. Includes tests and PC download for Windows 32 and 64-bit systems completely free-of-charge. Encryption • Strong requirements for a symmetric key encryption algorithm (cipher): – An opponent having one or more ciphertexts along with their corresponding plaintexts produced using a particular key should not be able to decrypt a given ciphertext or deduce the key. However, referring to something as "64-bit" encryption says nothing about the underlying encryption method. Farewell Hash, you will be missed a lot more than we think “We lost a bit of control for a while there,” Smith joked some days later. BitLocker, an encryption program from Microsoft, offers data protection for the whole disk in an efficient method that is easy to implement, seamless to the user, and can be managed by systems admins. SHA-1 produces a 160-bit (20-byte) hash value. How can I decrypt MD5? You can't! MD5 is NOT an encryption algorithm! A lot of people are under the impression that MD5 encrypts data. Can we do a 32 bit encryption in Mule. The problem with what you linked to is that, because of collisions, you cannot guarantee that the text that technique comes up with is the only string that generated that hash. • The meaning is as follows: • the first bit of the outputis taken from the 58th bit of the input; the second bit from. Since it will never exceed 256-bits for Maru 1 or 512 bits for Maru 2, there didn't seem any point using a 64-bit integer. DCPCrypt is hosted in a Git repository. 256 bit encryption is even stronger. … no one can't decrypt data that encrypted by 32 bit IV. While it's technically possible to reverse-hash something, the computing power required makes it unfeasible. You can generate the sha1 checksum of your. SSL uses public-key encryption to exchange a session key between the client and server; this session key is used to encrypt the http transaction (both request and response). Conclusion Developing Secure Hash Algorithm was initially major concern for defense authorities. Refer the link "How to determine whether a computer is running a 32-bit version or 64-bit version of the Windows operating system" to find which version of Operating System you have installed. Place an entry in the Input window and crypt or decrypt via Base64. The script works without problem and i got as an output a hex string 32 in length but it's not the md5 the result that i got with this script is not what i got with hashlib or md5 encryption website So please need you help to fix this problem Sorry about my english anyway that's the code :. And this fixed size output is what is called a hash. Like all computer data, hashes are large numbers, and are usually written as hexadecimal. To download the latest source code from the repository you need to run the. A total of 25,600 iterations. ) automatically. With the recent news of weaknesses in some common security algorithms (MD4, MD5, SHA-0), many are wondering exactly what these things are: They form the underpinning of much of our electronic infrastructure, and in this Guide we'll try to give an overview of what they are and how to understand them in the context of the recent developments. The usual way "get back" the string is by using a large set of strings to try to compute the MD5 hash to match against the known hash value. Sha-1 is an improvement of Sha-0, it was created by the NSA, and improve cryptographic security by increasing the number of operations before a collision (theory says 2^63 operations), however Sha-1 is not considered as secure because 2^63 could be reach pretty. Breathe Easy Bitcoiners, Quantum Computing No Match For Sha-2 Encryption to posit that hash functions and asymmetric encryption could defend not only against modern computers, but also against. Since March 2010, DCPCrypt source code is hosted as part of the Lazarus-CCR project on SourceForge. NET Description. Full-disk encryption is the process of encoding all user data on an Android device using an encrypted key. Blowfish is capable of strong encryption and can use key sizes up to 56 bytes (a 448 bit key). Second layer of encryption. How, or can I change to 64 bit?. The secure hash algorithm originally started out as SHA0 (a 160-bit hash published in 1993). Q: How secure is the encryption used by SSL? A: It would take significantly longer than the age of the universe to crack a 128-bit key. Let's say that you want to encrypt a nine-digit Social Security Number (SSN) using the Rijndael encryption algorithm with the 128-bit (16-byte) block size and PKCS #7 padding. 5 and the support of Windows 32-bit for EFI system encryption. This is a list of hash functions, including cyclic redundancy checks, checksum functions, and cryptographic hash functions. Given what we now know about the extent of the NSA’s assault on encryption standards, however, most experts agree that AES-256 provides a higher security margin. Linux Mint is free of charge (thanks to your donations and adverts on the website) and we hope you'll enjoy it. Cyclical Redundancy Check (CRC) 16- or 32-bit hash function that supports four CRC forms Advanced Encryption Standard (AES) Hardware accelerated data encryption and decryption based on 128-, 192-, and 256-bit keys Data Encryption Standard (DES) Block cipher implementation with 168-bit effective key length. I decided to make a simple, easy to remember mirror for the final release of DVD Decrypter. The contents of the files that you want to protect are encrypted by WinZip based on a password that you specify. By contrast MD5 has a 128-bit digest value and SHA-1 has a 160-bit digest value. It is also commonly used to check data integrity. Turn on device encryption. Hi C Gurus, I'm trying to find a hash algorithm with very specific and relatively simple requirements. However, CRC-32 is linear, which means that it is possible to compute the bit difference of two CRCs based on the bit difference of the messages over which they are taken. For both SHA-1 and SHA-256, one begins by converting the message to a unique representation of the message that is a multiple of 512 bits in length, without loss of information about its exact original length in bits, as follows: append a 1 to the message. 128 bit encryption is very secure and is hard to crack the code. I don't normally use secure hash functions in a 64 bit environment (pretty much only in 8 and 32 bit). Tool to decrypt/encrypt MD5 automatically. Encryption key lengths & hacking feasibility. With hash toolkit you could find the original password for a hash. This message digest is usually then rendered as a hexadecimal number which is 40 digits long. of the bit wise operators. 11i implementation of AES, a 128 bit key length is used. But this is difficult to achieve, and you should not assume (for example) running the same algorithm twice with different initial states will produce uncorrelated. Introduction to the SHA-256 hash function This article aims to give an introduction into the SHA-256 hash algorithm. Multi-platform Encryption supported across Windows 10, 8, 8. * murmurhash3_x64_128 is a good choice for longer strings or if you need more than 32 bits of hash. • Files are both compressed & encrypted, which results in a smaller file. Verifies the integrity and authenticity of a message with the use of a shared secret. All it does is compute a hash value for a given. a hash function for 32 and 64 bit pointers Hi Guys, I understand that a good hash function is hard to find, but this problem seems to get event more complicated when i tried to find a nice, efficient way to hash pointers. 100% Safe and Secure Free Download 32-bit Software Version. System Variables file_key_management_encryption_algorithm. Which hashing algorithm is best for uniqueness and speed? Example (good) uses include hash dictionaries. This hash value is known as a message digest. The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. Generally,. Public-key encryption is actually much more complex than this example, but that's the basic idea. While the hash function is to get blocks of data and return them with a fixed-size bit string or hash value. You cannot "decrypt" a hash back to the original content. As of when this article was published, there is currently a much more powerful SHA known as SHA3 (a 1600-bit hash). Both 32-bit and 64-bit systems are supported. property of memory encryption renders existing bit-level write reduction techniques ineffective. MD5, SHA1, SHA256, SHA512 and more. Indeed, you can compute a 64-bit hash function and make two 32-bit hash functions out of it: use the first 32 bits for the first hash function and the remaining 32 bits for the other. The HASH function included with DBMS_CRYPTO, is a one-way hash function that you can use to generate a hash value from either RAW or LOB data. How can it be, you might be wondering?. 128 bit encryption is very secure and is hard to crack the code. I have a task to perform and I would like to know if is possible to decrypt a hash key to know the original string value. SPECK Parameters. RSA:- It is an asymmetric cryptography, i. NOT RELEVANT with one-way hashes) GOST Hash — HMAC. NET and C++ provide different implementation to achieve this kind of encryption. Useful for security application, it can perform a check data integrity function. In AES, message is divided into block-size of 128 bits(16 bytes) to perform encryption or decryption operation. Common Hash Functions!MD5 •128-bit output •Still used very widely •Completely broken by now!RIPEMD-160 •160-bit variant of MD-5!SHA-1 (Secure Hash Algorithm) •160-bit output •US government (NIST) standard as of 1993-95 -Also the hash algorithm for Digital Signature Standard (DSS) slide 18 Basic Structure of SHA-1 Against padding. For instance, a function that creates a 256-bit hash (like SHA) will have fewer collisions than one that produces a 128-bit hash (like MD5) because there are more possible hash values when you have more bits. Some examples are given below: MD4 – It is a hash function created by Ronald Rivest in 1990. • Password protected. It depends on which encryption arithmetic you use. There are indeed many hash generators on the Internet. So I took 15 minutes (it's small!) to port the 32 bit version, since it should be faster than the other versions for small keys like document ids. Blockchain Hash Function. You can chose 128, 192 or 256-bit long. This site allows you to encrypt or decrypt any md5 hash, we have our own database with more than 10 million keys, also we look for your hash on 23+ others web sites. 32-bit and 64-bit versions of OSForensics are available.

MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value, specified in RFC 1321, MD5 is one in a series of message digest algorithms designed by Professor Ronald Rivest of MIT (Rivest, 1994). 0 Benchmarks. SPECK Parameters. Preparation code return murmurhash3_32_gc(this. One can’t perform an in-place or direct upgrade from 32-bit Windows 7/Windows 8. One should know that md5, although it's very used and common, shouldn't be use to encrypt critical data, since it's not secure anymore (collisions were found, and decrypt. Hash functions are used in computers and cryptography. MD5 Hash Generator This online tool allows you to generate the MD5 hash of any string. If Operating System is 64bit, then the Encryption will be 64bit one. Elaine Barker. Breathe Easy Bitcoiners, Quantum Computing No Match For Sha-2 Encryption to posit that hash functions and asymmetric encryption could defend not only against modern computers, but also against. All it does is compute a hash value for a given. The naïve answer seems to be “the longer the better”: the 256-bit encryption’s got to be much better than 128-bit one, why not use it? The reality, however, is that the 128-bit encryption is just as strong as the 256-bit, while it requires less computational resources and is performed a bit faster. Java has provided certain API's by which data can be encrypted using AES algorithm. Two security researchers from the French Institute for Research in Computer Science and Automation showed that practical collision attacks are now possible against 64-bit ciphers and recommended. Online Reverse Hash Lookup works with several online databases containing millions of hash values as well as engines using rainbow tables that can retrieve the plaintext messages in more sophisticated way. MD5 is a cryptographic hash function. As an important reminder, the best protection against ransomware is preventing it from ever reaching your system. The RijndaelManaged 256-bit encryption is a derivative of the 32 bytes in the key. Data Encryption Standard (DES): Data Encryption Standard (DES) is an early data encryption algorithm that encrypts data with a 56-bit, randomly generated symmetric key to encrypt/decrypt 64-bit blocks of data. Suite B Cryptography March 22, 2006. Hashing algorithms generate a fixed-length hash code regardless of the length of the input. The key is derived from several characteristics passed to encryption and decryption routines. So, by this logic, a 64-bit encryption string is always worse than one with a higher number. Security question, please solve. LM Password Hashes The LAN Manager hash was one of the first password hashing algorithms to be used by Windows operating systems, and the only version to be. Supported hashes for decryption:. There is a very small possibility of getting two identical hashes of two different files. Given what we now know about the extent of the NSA’s assault on encryption standards, however, most experts agree that AES-256 provides a higher security margin. Yes, 32 is weak, but if I could concatenate keys, it would be no problem to have four words for a 64 bit key. Herein are very highly optimized 32-bit and 64-bit Fnv-1a hashing functions.
