Web22 Apr 2024 · SHA-256, which stands for secure hash algorithm 256, is a cryptographic hashing algorithm (or function) that’s used for message, file, and data integrity verification. It’s part of the SHA-2 family of hash functions and uses a 256-bit key to take a piece of data and convert it into a new, unrecognizable data string of a fixed length. WebDesign of Hashing Algorithms. At the heart of a hashing is a mathematical function that operates on two fixed-size blocks of data to create a hash code. This hash function forms the part of the hashing algorithm. The size of each data block varies depending on the algorithm. Typically the block sizes are from 128 bits to 512 bits. millennium chess computer website
