Frequently asked questions
Which algorithm should I use?
Use SHA-256 or SHA-512 for security-related work (passwords, signatures, integrity). MD5 and SHA-1 are broken for security but still useful as fast checksums.
Is my input sent anywhere?
No. All hashing runs in your browser using Web Crypto for SHA family and a bundled MD5 library. Nothing leaves your device.
Can I reverse a hash?
No, hashes are one-way functions. You can however precompute hashes of common values (rainbow tables), which is why hashing alone isn't safe for passwords.
