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.

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).
To learn a password from a hash is to find a string which, when input into the hash function, creates that same hash. This is the same as inverting the hash function. Though brute-force attacks (e.g. dictionary attacks ) may be used to try to invert a hash function, they can become infeasible when the set of possible passwords is large enough.
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.
Therefore, Alice sends a hashed version of her password instead, like in CRAM-MD5 or DIGEST-MD5. As it is a hash, Mallory doesn't get the password itself. As the hash is salted with a challenge, Mallory could use it only for one login process.
MurmurHash is a non-cryptographic hash function suitable for general hash-based lookup. [1] [2] [3] It was created by Austin Appleby in 2008 [4] and, as of 8 January 2016, [5] is hosted on GitHub along with its test suite named SMHasher.
