NAME

Crypt::Passwd::XS - Full XS implementation of common crypt() algorithms

SYNOPSIS

  use Crypt::Passwd::XS;

  my $plaintext = 'secret';
  my $salt      = '$1$1234';
  my $crypted   = Crypt::Passwd::XS::crypt( $plaintext, $salt );

DESCRIPTION

This module provides several common crypt() schemes as full XS implementations. It allows you to validate crypted passwords that were hashed using a scheme that the system's native crypt() implementation does not support.

Description of functions

The crypt() function handles all supported crypt methods using the standard salt prefix system for determinging the crypt type.

The unix_md5_crypt() function performs a MD5 crypt regardless of the salt prefix.

The apache_md5_crypt() function performs a APR1 crypt regardless of the salt prefix.

The unix_des_crypt() funtion performs a traditional DES crypt regardless of the salt prefix.

The unix_sha256_crypt() function performs a SHA256 crypt regardless of the salt prefix.

The unix_sha512_crypt() function performs a SHA512 crypt regardless of the salt prefix.

TODO

The blowfish and Sun crypt() schemes are currently unsupported.
