SHA-256 Generator

SHA-256 produces a 256-bit digest usually displayed as 64 hexadecimal characters.

It is widely used for integrity checks and modern cryptographic workflows when applied correctly.

The tool should generate a SHA-256 digest from input text using a clear byte encoding.

Validation examples should identify non-hex characters and incorrect digest lengths.

SHA-256 is deterministic: the same bytes always produce the same digest.

Hashing text depends on the bytes used, so input encoding must be clear.

Reference material should cover SHA-256 digest size, hexadecimal output, and common use cases.

Future notes can separate raw hashing from HMAC and password hashing.

Developer examples should show hashing UTF-8 text and validating a known digest.

Examples should warn that password storage needs dedicated password-hashing algorithms.
