Frequently asked questions

Which hash algorithms are supported?

MD5, SHA-1, SHA-256, and SHA-512 — all four are computed at once from the same input.

Is MD5 or SHA-1 safe to use for security?

No — both are cryptographically broken and shouldn't protect passwords or sensitive data. They're included because they're still widely used for checksums and matching against publicly published hash values, not for security.

Is my text sent to a server to be hashed?

No — SHA-1/256/512 use your browser's built-in Web Crypto API, and MD5 runs via a small local JavaScript implementation. Both happen entirely on your device.
