SHA-512/256 Hash Generator

Generate a SHA-512/256 message digest from text input. Paste or type text, select Generate hash, and the tool returns the 256-bit digest as 64 lowercase hexadecimal characters.

Question

What is SHA-512/256?

SHA-512/256 is a SHA-2 cryptographic hash function standardized by NIST in FIPS 180-4. It produces a 256-bit message digest that is normally displayed as 64 hexadecimal characters and is distinct from both SHA-256 and full SHA-512.

This tool hashes the text you enter as UTF-8 bytes and writes the resulting SHA-512/256 digest to the output box without sending the text to a server. Whitespace, punctuation, letter case, line endings, and non-ASCII characters all affect the result, so compare outputs only with systems that hash the same text encoding.

Use SHA-512/256 for published test vectors, checksum comparisons, protocol examples, and interoperability work when a standard or system explicitly names SHA-512/256. If a system asks for SHA-256, SHA-384, SHA-512, SHA-3, or another digest algorithm, use the exact algorithm it names.

A SHA-512/256 digest is deterministic, but it is not encryption and cannot be decoded back to the original text. It is also not a password storage scheme or a message authentication code; use a salted password hashing algorithm for passwords and a keyed integrity mechanism when authenticity is required.
