Generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text online, computed in your browser.
Compute a cryptographic hash of any text with MD5, SHA-1, SHA-256, SHA-384 or SHA-512. The digest is calculated locally with the Web Crypto API (MD5 is implemented in JS), so your input never leaves the page.
SHA-256 is the safe default for integrity and fingerprints. MD5 and SHA-1 are fine for checksums but broken for security — never use them for passwords or signatures.
No. Hashing is one-way. "Reversal" only works via lookup tables for common inputs, which is why salting matters for stored secrets.
