WebJan 25, 2024 · A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier. So, why do we call it a one-way function? 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.
