WebJun 22, 2024 · Hashing is a cryptography method that converts any form of data to a unique text string. Any piece of data can be hashed, regardless of its size or type. In … 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:
