.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides several common \fIcrypt()\fR schemes as full \s-1XS\s0 implementations.
It allows you to validate crypted passwords that were hashed using a scheme
that the system's native \fIcrypt()\fR implementation does not support.
.SS "Description of functions"
.IX Subsection "Description of functions"
The \fB\f(BIcrypt()\fB\fR function handles all supported crypt methods using the standard
salt prefix system for determinging the crypt type.
.PP
The \fB\f(BIunix_md5_crypt()\fB\fR function performs a \s-1MD5\s0 crypt regardless of the salt
prefix.
.PP
The \fB\f(BIapache_md5_crypt()\fB\fR function performs a \s-1APR1\s0 crypt regardless of the salt
prefix.
.PP
The \fB\f(BIunix_des_crypt()\fB\fR funtion performs a traditional \s-1DES\s0 crypt regardless of
the salt prefix.
.PP
The \fB\f(BIunix_sha256_crypt()\fB\fR function performs a \s-1SHA256\s0 crypt regardless of the
salt prefix.
.PP
The \fB\f(BIunix_sha512_crypt()\fB\fR function performs a \s-1SHA512\s0 crypt regardless of the
salt prefix.
.SH "TODO"
.IX Header "TODO"
The blowfish and Sun \fIcrypt()\fR schemes are currently unsupported.
