andrewboyson | 0:be515c9019e3 | 1 | SHA |
andrewboyson | 0:be515c9019e3 | 2 | secure hash algorithm |
andrewboyson | 0:be515c9019e3 | 3 | - it is deterministic, meaning that the same message always results in the same hash |
andrewboyson | 0:be515c9019e3 | 4 | - it is quick to compute the hash value for any given message |
andrewboyson | 0:be515c9019e3 | 5 | - it is infeasible to generate a message that yields a given hash value |
andrewboyson | 0:be515c9019e3 | 6 | - it is infeasible to find two different messages with the same hash value |
andrewboyson | 0:be515c9019e3 | 7 | - a small change to a message should change the hash value so extensively that |
andrewboyson | 0:be515c9019e3 | 8 | the new hash value appears uncorrelated with the old hash value (avalanche effect) |
andrewboyson | 0:be515c9019e3 | 9 | |
andrewboyson | 0:be515c9019e3 | 10 | HMAC |
andrewboyson | 0:be515c9019e3 | 11 | keyed-hash message authentication code or hash-based message authentication code |
andrewboyson | 0:be515c9019e3 | 12 | - it is a message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. |
andrewboyson | 0:be515c9019e3 | 13 | - it may be used to simultaneously verify both the data integrity and the authentication of a message |
andrewboyson | 0:be515c9019e3 | 14 | - used to sign a message with a symmetrical key |
