Hash Generator

Compute MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 hashes of any text or file — with HMAC signing and checksum verification. Verify downloads and sign payloads in seconds.

Input text

Hashed as UTF-8, exactly as typed — whitespace counts.

HMAC modeSign the input with a secret key (SHA family only).

Verify a checksumoptional

Paste an expected hash — it's compared against every digest above.

Digests

Type some text or pick a file to hash.

Your text, files and keys are never stored or logged. MD5, SHA-1 and CRC32 are fine as checksums but broken for security — prefer SHA-256 or stronger.
