<font size=+1><i>STRING</i> <b>crypt</b>(<i>STRING <b>str</b>, STRING <b>salt</b></i>)</font>
<p>This function performs one-way encryption on <VAR>str</VAR>, using the
host system's <CODE>crypt()</CODE> library routine. If <VAR>salt</VAR> is
specified, then it must be a two-character string; otherwise, a salt is
chosen randomly. The return value of <CODE>crypt()</CODE> is the encrypted
string.
<P>The encryption performed by this function has the property that it is
very difficult to find a string which will produce a given result;
however, a given string and a given salt will always yield the same
encrypted string.
<P>Examples:
<blockquote>
<PRE>
crypt("foo", "ab")
=> "abQ9KY.KfrYrc"
</PRE>
