Frequently Asked Questions

Does this upload my text anywhere?
No — hashing happens entirely in your browser using the Web Crypto API.
Why isn't MD5 included?
Browsers' built-in Web Crypto API doesn't support MD5 (it's considered cryptographically broken and was deliberately excluded) — SHA-1, SHA-256, and SHA-512 are supported natively and shown here instead.
Is SHA-1 still safe to use?
SHA-1 is no longer considered secure against determined attackers for cryptographic purposes (e.g. digital signatures) — use SHA-256 or SHA-512 for anything security-sensitive.
