  2. MD5 - Wikipedia

    en.wikipedia.org/wiki/MD5

    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.

  3. Digest access authentication - Wikipedia

    en.wikipedia.org/wiki/Digest_access_authentication

    Digest access authentication prevents the use of a strong password hash (such as bcrypt) when storing passwords (since either the password, or the digested username, realm and password must be recoverable) Also, since the MD5 algorithm is not allowed in FIPS, HTTP Digest authentication will not work with FIPS-certified [note 1] crypto modules.

  4. Cryptographic hash function - Wikipedia

    en.wikipedia.org/wiki/Cryptographic_hash_function

    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).

  6. md5sum - Wikipedia

    en.wikipedia.org/wiki/Md5sum

    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.

  7. Message authentication code - Wikipedia

    en.wikipedia.org/wiki/Message_authentication_code

    Informally, a message authentication code system consists of three algorithms: A key generation algorithm selects a key from the key space uniformly at random. A MAC generation algorithm efficiently returns a tag given the key and the message. A verifying algorithm efficiently verifies the authenticity of the message given the same key and the tag.

  8. Orders of magnitude (data) - Wikipedia

    – minimum cipher strength of the Rijndael and AES encryption standards, and of the widely used MD5 cryptographic message digest algorithm – size of an SSE vector register, included as part of the x86-64 standard 160 bits (20 bytes) – maximum key length of the SHA-1, standard Tiger (hash function), and Tiger2 cryptographic message digest ...

  9. SHA-1 - Wikipedia

    en.wikipedia.org/wiki/SHA-1

    SHA-1 produces a message digest based on principles similar to those used by Ronald L. Rivest of MIT in the design of the MD2, MD4 and MD5 message digest algorithms, but generates a larger hash value (160 bits vs. 128 bits). SHA-1 was developed as part of the U.S. Government's Capstone project. [19]
