MD5 and algorithm
Any cryptographic hash function, such as MD5 or SHA-1, may be used in the calculation of an HMAC ; the resulting MAC algorithm is termed HMAC-MD5 or HMAC-SHA1 accordingly.
* The pseudorandom function splits the input data in half and processes each one with a different hashing algorithm ( MD5 and SHA-1 ), then XORs them together to create the MAC.
The underlying MD5 algorithm is no longer deemed secure, thus while md5sum is well-suited for e. g. identifying known files in situations that are not security related, it should not be relied on if there is a chance that files have been purposefully and maliciously tampered.
In cryptography, MD5CRK was a distributed effort ( similar to distributed. net ) launched by Jean-Luc Cooke and his company, CertainKey Cryptosystems, to demonstrate that the MD5 message digest algorithm is insecure by finding a collision — two messages that produce the same MD5 hash.
* Integrity-RSVP messages are appended with a message digest created by combining the message contents and a shared key using a message digest algorithm ( commonly MD5 ).
– minimum cipher strength of the Rijndael and AES encryption standards, and of the widely used MD5 cryptographic message digest algorithm
** "$ id $ salt $ hashed ", where "$ id " is the hashing algorithm used ( On GNU / Linux, "" stands for MD5, "" is Blowfish, "" is SHA-256 and "" is SHA-512, crypt ( 3 ) manpage, other Unix may have different values, like NetBSD ).
The Flame malware successfully used a new variation of a chosen-prefix collision attack to spoof code signing of its components by a Microsoft root certificate that still used the compromised MD5 algorithm.
This was further modified in iTunes 4. 5 to use a custom hashing algorithm, rather than the standard MD5 function used previously.
MD5 and 5
However, the program will not decrypt ' Type 5 ' passwords or passwords set with the enable secret command, which uses salted MD5 hashes.
; OCaml: The uuidm library implements universally unique identifiers version 3, 5 ( name based with MD5, SHA-1 hashing ) and 4 ( random based ) according to RFC 4122.
Message and Digest
RIPEMD-160 ( RACE Integrity Primitives Evaluation Message Digest ) is a 160-bit message digest algorithm ( cryptographic hash function ) developed in Leuven, Belgium, by Hans Dobbertin, Antoon Bosselaers and Bart Preneel at the COSIC research group at the Katholieke Universiteit Leuven, and first published in 1996.
