Tiger (cryptography)

Tiger is a cryptographic hash function, designed by Ross Anderson and Eli Biham in 1996. The hash value generated by Tiger has a length of 192 bits. The tiger algorithm is not patented. Test vectors for the successor named Tiger2 are already available.

Tiger hashes

The 192 bits ( 24 bytes ) long tiger hashes are usually listed as 48 - digit hexadecimal number. The following example shows a 59 -byte ASCII input and the associated Tiger hashes:

Tiger ( " quick brown fox completely dilapidated taxi across Bavaria ") =   4df42db66c8d84269d4b7157b92a87be717aa1a5834a3050   Tiger2 ( " quick brown fox completely dilapidated taxi across Bavaria ") =   ac228a08cc97a449d85729e6549dbe4cd746df0061522b2c A small change in the message is typically produced a completely different hash. With Frank instead Franz gives:

Tiger ( " Frank chases in the completely dilapidated taxi across Bavaria ") =   9cee0eb7b596ba0f435d42c33ddf8eff7fabb86922aa4bc6   Tiger2 ( " Frank chases in the completely dilapidated taxi across Bavaria ") =   5959793d7837abf2cc44dc57b3712c6da5d89cc1df92cd5a The hash of a string of zero length is:

Tiger ("") =   3293AC630C13F0245F92BBB1766E16167A4E58492DDE73F3   Tiger2 ("") =   4441be75f6018773c206c22745374b924aa8313fef919f41 Web Links
