WebApr 10, 2024 · Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions. WebSM3 Hash is a cryptographic hash function similar to SHA-3. However, it has different design principles, and it targets specific security requirements. SM3 Hash follows the Merkle-Damgard construction, which divides the input message into blocks and applies a compression function to each block iteratively.
