The SHA-256 (Secure Hash Algorithm 256) generator is a tool that creates a unique, fixed-length fingerprint (also known as a hash or checksum) from an input of any length. The SHA-256 algorithm produces a 256-bit hash value.
Like other cryptographic hash functions, the SHA-256 generator is used for data integrity checks to ensure that files have not been altered during transmission or storage. The hash value generated by the SHA-256 generator is unique to the input, and even a small change in the input will result in a completely different hash value.
SHA-256 is considered to be a secure hash function and is widely used in various cryptographic applications, such as digital signatures, message authentication codes, and key derivation functions.
