SHA-256 Hash Generator

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hashing function that takes an input and produces a fixed 256-bit (32-byte) hash value, regardless of the input size. It is part of the SHA-2 family of algorithms, designed by the National Security Agency (NSA), and is widely used for data integrity verification and secure password storage. The hashing process is deterministic, meaning the same input will always produce the same hash, but even a minor change in the input results in a completely different hash, a property known as the avalanche effect. SHA-256 is a one-way function, making it computationally infeasible to reverse-engineer the original input from its hash, ensuring security in applications like digital signatures, blockchain technology, and SSL certificates.
