[{$pagename}] is both 
* [Cryptographic Hash Function] and
* An Application to create and change passwords on [NIX] systems

!! [Cryptographic Hash Function] 
Cryptographic Hash Function is used both to generate a new hash for storage and also to hash a proffered password with a recorded salt for comparison.

Modern Unix implementations of the [{$pagename}] library routine support a variety of different [Ciphers]. 

The particular [Cryptographic Hash Function] used can be identified by a unique code prefix in the resulting hashtext, following a pseudo-standard called Modular Crypt Format.
