Frequently asked questions

Is SHA-1 still secure?

SHA-1 is considered cryptographically broken for collision resistance and shouldn't be used for security. It's still fine for checksums, legacy compatibility and non-security identifiers.

Is my text sent to a server?

No. Hashing runs entirely in your browser via the Web Crypto API, so your input never leaves your device.
