Cryptographic security
WebTypes of security of hash functions [ edit] Generally, the basic security of cryptographic hash functions can be seen from different angles: pre-image resistance, second pre-image resistance, collision resistance, and pseudo-randomness. Pre-image resistance: given a hash. h {\displaystyle h} it should be hard to find any message.
