Adler-32 is a checksum algorithm which was invented by Mark Adler in 1995, and is a modification of the Fletcher checksum.The equivalent standard used by other member-states of the CIS is GOST 34.311-95. It was initially defined in the Russian national standard GOST R 34.11-94 Information Technology – Cryptographic Information Security – Hash Function. The GOST hash function, defined in the standards GOST R 34.11-94 and GOST 34.311-95 is a 256-bit cryptographic hash function.It was named after the Egyptian Pharaoh Sneferu, continuing the tradition of the Khufu and Khafre block ciphers. Snefru is a cryptographic hash function invented by Ralph Merkle in 1990 while working at Xerox PARC. The function supports 128-bit and 256-bit output.

Unlike the SHA-2 family, no distinguishing initialization values are defined they are simply prefixes of the full Tiger/192 hash value. Truncated versions (known as Tiger/128 and Tiger/160) can be used for compatibility with protocols assuming a particular hash size.
The size of a Tiger hash value is 192 bits. In cryptography, Tiger is a cryptographic hash function designed by Ross Anderson and Eli Biham in 1995 for efficiency on 64-bit platforms.It was designed by Vincent Rijmen (co-creator of the Advanced Encryption Standard) and Paulo S. In computer science and cryptography, Whirlpool (sometimes styled WHIRLPOOL) is a cryptographic hash function.There are five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, of which RIPEMD-160 is the most common.
RIPEMD ( RIPE Message Digest) is a family of cryptographic hash functions developed in 1992 (the original RIPEMD) and 1996 (other variants). In fact, it is widely used in different technologies including Bitcoin and other cryptocurrency protocols. SNEFRU-256 also exists but is not currently supported on this site.Ĭryptographic hashing has been an integral part of the cybersecurity spectrum. HAVAL128) represents the output size, and the number following the comma (as in HAVAL128,3) represents the "rounds" or "passes" it makes (each pass making it more secure, in theory & some aspects). HAVAL is a flexible algorithm that can produce 128, 160, 192, 224, or 256-bit hashes. It produces 128-bit digests, thus the "128" after the name.Ī patent-free algorithm designed in 1995 originally to be optimized for 64-bit DEC Alpha, TIGER today produces fast hashing with security probably on the same order as the SHA2 group or better. RIPEMD-128 is a drop-in replacement for the RIPEMD-160 algorithm. Whirlpool is a standardized, public domain hashing algorithm that produces 512 bit digests. GOST is a Russian National Standard hashing algorithm that produces 256-bit message digests. The SHA2 group, especially SHA-512, is probably the most easily available highly secure hashing algorithms available.ĬRC32 is a common algorithm for computing checksums to protect against accidental corruption and changes.Īdler-32 is used as a part of the zlib compression function and is mainly used in a way similar to CRC32, but might be faster than CRCs at a cost of reliability.īased on the GOST 28147-89 Block Cipher. MD5 is an extremely popular hashing algorithm but now has very well known collision issues. MD2 is a weak algorithm invented in 1989, still used today in some public key cryptography. Unlike other cryptographic algorithms, the keys have no hash functions. Generally the length of the output hashes is less than the corresponding length of the input code. Output is generally referred to as hash values, hash codes, hash amounts, checksums, digest file, digital fingerprint or simply hashes. 
Message Digest (hash) allows direct processing of arbitrary length messages using a variety of hashing algorithms to output an fixed length text.
