MD5

Technique

A widely used cryptographic hash function producing a 128-bit digest, once common for checksums and password storage but now considered cryptographically broken because deliberate collisions, two different inputs sharing the same digest, can be constructed efficiently.

  • History and cryptanalysis
    When analytic work indicated that MD5's predecessor MD4 was likely to be insecure, Rivest designed MD5 in 1991 as a secure replacement.
  • Introduction
    The MD5 message-digest algorithm is a widely used hash function producing a 128-bit hash value.
