Definition of cryptographic hash function PCMag

WebTo be considered cryptographically secure, the hash function should meet two requirements: It is impossible for an attacker to generate a message matching a specific hash value. It is impossible for an attacker to create two messages that produce the same hash value. Most cryptographic hash functions are designed to take a string of any length as input and produce a fixed-length hash value. A cryptographic hash function must be able to withstand all known types of cryptanalytic attack. In theoretical cryptography, the security level of a cryptographic hash function has been defined using the following properties: biotree.cn
