 ## [PBKDF2](pbkdf2.md)
 If you use a password longer than 64 bytes and hash it with **PBKDF2-HMAC-SHA1**, it is first *pre-hashed* with SHA1, so `PBKDF2-HMAC-SHA1(password1) === PBKDF2-HMAC-SHA1(password2)` because `sha1(password1) === bin2hex(password2)`.
 
+## [Tiger/192,3](tiger192,3.md) and [SHA-224](sha224.md)
+Right now there's just one magic hash in each thanks to [Norbert Tihanyi](https://twitter.com/TihanyiNorbert), more will be hopefully added in the future.

 ### Conclusion
 Use `===` when comparing anything* in PHP, not `==`. And use [`password_hash()`](https://php.net/function.password-hash) and [`password_verify()`](https://php.net/function.password-verify) for password hashing in PHP, don't use MD5 or SHA-1. *Use [`hash_equals()`](https://php.net/function.hash-equals) when comparing hashes.
