Generate SHA-256, SHA-1, SHA-512, MD5 hashes

Paste any text and instantly get its cryptographic hash. SHA-256, SHA-1, and SHA-512 use your browser’s built-in Web Crypto API. MD5 uses a lightweight client-side implementation. Everything runs locally – your input never leaves this tab.

Best for: file integrity checks, version tracking, comparing two large blobs without uploading them, generating fingerprints. Not for password storage – use bcrypt or Argon2 for that.
