WebIn cryptography, Tiger is a cryptographic hash function designed by Ross Anderson and Eli Biham in 1995 for efficiency on 64-bit platforms. The size of a Tiger hash value is 192 bits. Truncated versions (known as Tiger/128 and Tiger/160) can be used for compatibility with protocols assuming a particular hash size. WebHash functions are used for message security, password security, computer forensics and cryptocurrency. Ronald Rivest, founder of RSA Data Security LLC and professor at Massachusetts Institute of Technology, designed MD5 in 1991 as an improvement to a prior message-digest algorithm, MD4.

WebApr 13, 2014 · the hash is H n. If we use AES-256, we obtain a 128 -bit hash, with n = ⌊ ( l + 320) / 256 ⌋ AES encryptions (and sub-key derivations) where l is the message length in bits. There are other constructions, but this is the less inefficient we have when using one of the three AES ciphers.
