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.
md5deep exists for Windows and most Unix-based systems, including OS X. It is present in OS X's Fink, Homebrew and MacPorts projects. Binary packages exist for most free Unix systems. Many vendors initially resist including md5deep as they mistakenly [citation needed] believe its functions can be reproduced with one line of shell scripting. [1]
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.

Rainbow tables are specific to the hash function they were created for e.g., MD5 tables can crack only MD5 hashes. The theory of this technique was invented by Philippe Oechslin [3] as a fast form of time/memory tradeoff, [1] which he implemented in the Windows password cracker Ophcrack.
Hash functions are used in conjunction with hash tables to store and retrieve data items or data records. The hash function translates the key associated with each datum or record into a hash code, which is used to index the hash table.
