Hash Generator
Computes MD5, SHA-1, SHA-256 and SHA-512 digests of UTF-8 text as it is typed, and guesses a hash's type from its length and format (hex length, bcrypt, $5$ and $6$ crypt, Base64 SHA-256); length alone cannot tell SHA-256 from SHA3-256. MD5 is RFC 1321 (1992); SHA-1 and SHA-2 are FIPS 180-4. MD5 collisions were published in 2004, and RFC 6151 rules it out where collision resistance is needed.
