Frequently asked questions

What's the difference between SHA-256 and SHA-512?▼

SHA-256 produces a 256-bit (64-character) hash, while SHA-512 produces a 512-bit (128-character) hash. SHA-256 is the most commonly used for general purposes.

Is this the same as encryption?▼

No. Hashing is a one-way operation — you cannot reverse a hash to get the original text. Encryption is two-way and can be decrypted.

Is my data safe?▼

Yes. All hashing happens locally in your browser using the Web Crypto API. Nothing is sent to any server.
