SHA Hash Generator
Compute a cryptographic hash of any string with SHA-1, SHA-256 or SHA-512. Hashing runs on the browser's built-in Web Crypto API — nothing is sent to a server.
Frequently asked questions
Can a hash be reversed back to text?
No, hash functions are one-way. But identical input always yields an identical hash — that's how file integrity is verified.
Why is there no MD5?
MD5 is cryptographically broken and not supported by the Web Crypto API. Use SHA-256 for integrity checks.
