SHA-256, part of the SHA-2 (Secure Hash Algorithm 2) family, is a widely used cryptographic hash function. It produces a fixed-size 256-bit hash value, providing a higher level of security compared to its predecessor, SHA-1. SHA-256 is employed for various cryptographic applications, including digital signatures and data integrity verification. It takes an input and generates a unique hash, making it computationally infeasible for different inputs to produce the same output.
