Hash Engine. REP XSHA1: F3 0F A6 C8: Compute a cryptographic hash (using the SHA-1 and SHA-256 functions, respectively). ES:rSI points to data to compute a hash for, ES:rDI points to a message digest and rCX specifies the number of bytes. rAX should be set to 0 at the start of a calculation.

The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value. MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function MD4, [3] and was specified in 1992 as RFC 1321. MD5 can be used as a checksum to verify data integrity against unintentional corruption.
The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.
The first chain assumes the hash value is in the last hash position and just applies R k; the next chain assumes the hash value is in the second-to-last hash position and applies R k−1, then H, then R k; and so on until the last chain, which applies all the reduction functions, alternating with H. This creates a new way of producing a false ...
MD5 was designed by Ronald Rivest in 1991 to replace an earlier hash function, MD4, and was specified in 1992 as RFC 1321. Collisions against MD5 can be calculated within seconds, which makes the algorithm unsuitable for most use cases where a cryptographic hash is required. MD5 produces a digest of 128 bits (16 bytes).
The name md5deep is misleading. Since version 2.0, the md5deep package contains several different programs able to perform MD5, SHA-1, SHA-256, Tiger192 and Whirlpool digests, each of them named by the digest type followed by the word "deep". Thus, the name may confuse some people into thinking it only provides the MD5 algorithm when the ...
algorithm fnv-1 is hash := FNV_offset_basis for each byte_of_data to be hashed do hash := hash × FNV_prime hash := hash XOR byte_of_data return hash. In the above pseudocode, all variables are unsigned integers. All variables, except for byte_of_data, have the same number of bits as the FNV hash. The variable, byte_of_data, is an 8-bit ...
