Securing Data One Block at a Time – SHA 256 Algorithm Explained
SHA 256 is a cryptographic hashing algorithm that turns any input into a fixed-length digital fingerprint, making it nearly impossible to reverse or fake.
SHA 256 stands for Secure Hash Algorithm 256-bit. It is one of the most widely used cryptographic hash functions in the world and is a core building block of modern digital security. You will find it in blockchain systems like Bitcoin, password protection, file integrity checks, digital signatures, and secure communications.
