Frequently asked questions

Is it safe to hash sensitive passwords here?
Yes. All hashing occurs locally in your browser’s JavaScript/WebCrypto engine. No input text or generated hashes are transmitted to any server.
Which hash algorithm is recommended for security?
SHA-256 or SHA-512 is strongly recommended for cryptographic security and integrity checks. MD5 and SHA-1 are kept for legacy compatibility and checksums.
What do I need to enter?
Just Input Plaintext or String. Every field has a sensible default you can start from.
Is my data uploaded anywhere?
No. The calculation runs in your browser with JavaScript — nothing you type is sent to a server or stored.
Does it work on a phone?
Yes. The layout adapts to small screens and needs no app or signup.
