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.
For instance, MD5-Crypt uses a 1000 iteration loop that repeatedly feeds the salt, password, and current intermediate hash value back into the underlying MD5 hash function. [4] The user's password hash is the concatenation of the salt value (which is not secret) and the final hash.
md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash.

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).
Wang was born in Zhucheng, Shandong Province.She gained bachelor's (1987), master's (1990) and doctorate (1993) degrees at Shandong University, and subsequently lectured in the mathematics department from 1993. [2]
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 package supports many more.
It can, for example, potentially locate deleted emails [2] and scan a disk for text strings to use them as a password dictionary to crack encryption. [3] FTK is also associated with a standalone disk imaging program called FTK Imager. This tool saves an image of a hard disk in one file or in segments that may be later on reconstructed.
