Home › Developer Tools › Hash Generator
Type or paste text and get its MD5, SHA-1, SHA-256, SHA-512 and CRC32 hashes instantly. Everything is calculated in your browser — the text is never sent anywhere, so it is safe for sensitive strings.
—————A hash turns any input into a fixed-length fingerprint. Change one character and the fingerprint changes completely. SHA-256 is the modern general-purpose choice. MD5 and SHA-1 are broken for security purposes (collisions exist) but still fine as quick checksums. CRC32 is a fast error-check, not a security hash. Important: hashes cannot be "decrypted" — they are one-way by design, and any site promising SHA decryption is fake.
No. Hashing is one-way. The only "reversal" is guessing inputs and comparing — which is why passwords must be hashed with slow, salted algorithms like bcrypt or Argon2, not plain SHA.
The calculation is instant and local, so the tool recomputes on every keystroke.
