======crypt======

<box>
Calculate the hash of a [[PTPScript:Types:String|String]], using DES or alternatives on the system.

\\
**Syntax**
  * ''[[PTPScript:Types:String|String]] crypt( [[PTPScript:Types:String|String]] subject [, [[PTPScript:Types:String|String]] salt ] )''

\\
**Parameters**
  * [[PTPScript:Types:String|String]] ''subject'' - The String to calculate a hash for.
  * [[PTPScript:Types:String|String]] ''salt'' - An optional String to salt the encryption with. If no salt is specified, one is randomly generated.

\\
**Result**
  * [[PTPScript:Types:String|String]] - The encrypted hash.
</box>

Returns the encrypted hash of ''subject''. The hash returned depends upon what encryption algorithms are available on the system.
