 Secure Hash Algorithms

Secure Hash Algorithms (SHA) are a family of cryptographic hash functions designed to provide a fixed-size output (the hash) from arbitrary-sized input data. These algorithms are commonly used in various applications, including data integrity verification, digital signatures, password hashing, and more. The SHA family includes several different algorithms, each defined by the National Institute of Standards and Technology (NIST) in the Federal Information Processing Standards (FIPS).
