Frequently asked questions

Is it safe to hash or encode sensitive text here?
Hashing and encoding happen entirely client-side, so the input never reaches a server. That said, treat any web page with the same caution you would any other tool when working with production secrets.
Which hashing algorithms are supported?
FreeToolsNets covers MD5, SHA-1, SHA-256, SHA-512 and HMAC, using your browser's built-in Web Crypto API where possible for speed and accuracy.
