Frequently asked questions
- Which hash algorithms are supported?
- MD5, SHA-1, SHA-256, and SHA-512 are computed from the UTF-8 bytes of your input.
- Is MD5 computed locally too?
- Yes. SHA hashes use the Web Crypto API and MD5 uses a built-in implementation, all running in your browser.
- Does it upload my text?
- No. Hashing happens entirely in your browser and nothing is sent anywhere.
