NAME

       Crypt::PasswdMD5 - Provides interoperable MD5-based crypt() functions

SYNOPSIS

	   use Crypt::PasswdMD5;

	   $cryptedpassword = unix_md5_crypt($password, $salt);
	   $apachepassword = apache_md5_crypt($password, $salt);

DESCRIPTION

       the "unix_md5_crypt()" provides a crypt()-compatible interface to the rather new MD5-based crypt() function found in modern operating
       systems.  It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE and contains the following license in it:

	"THE BEER-WARE LICENSE" (Revision 42):
	<phk@login.dknet.dk> wrote this file.  As long as you retain this notice you
	can do whatever you want with this stuff. If we meet some day, and you think
	this stuff is worth it, you can buy me a beer in return.   Poul-Henning Kamp

       "apache_md5_crypt()" provides a function compatible with Apache's ".htpasswd" files. This was contributed by Bryan Hart <bryan@eai.com>.
       As suggested by William A. Rowe, Jr. <wrowe@lnd.com>, it is exported by default.

       For both functions, if a salt value is not supplied, a random salt will be generated.  Contributed by John Peacock <jpeacock@cpan.org>.

   EXPORT
       None by default.

NAME

       md5crypt - MD5-based password encryption

SYNOPSIS

       package require Tcl  8.2

       package require md5  2.0

       package require md5crypt  ?1.1.0?

       ::md5crypt::md5crypt password salt

       ::md5crypt::aprcrypt password salt

       ::md5crypt::salt ?length?

_________________________________________________________________

DESCRIPTION

       This  package  provides	an implementation of the MD5-crypt password encryption algorithm as pioneered by FreeBSD and currently in use as a
       replacement for the unix crypt(3) function in many modern systems. An implementation of the closely related Apache MD5-crypt is also avail-
       able.  The output of these commands are compatible with the BSD and OpenSSL implementation of md5crypt and the Apache 2 htpasswd program.

COMMANDS

       ::md5crypt::md5crypt password salt
	      Generate a BSD compatible md5-encoded password hash from the plaintext password and a random salt (see SALT).

       ::md5crypt::aprcrypt password salt
	      Generate an Apache compatible md5-encoded password hash from the plaintext password and a random salt (see SALT).

       ::md5crypt::salt ?length?
	      Generate a random salt string suitable for use with the md5crypt and aprcrypt commands.

SALT

       The salt passed to either of the encryption schemes implemented here is checked to see if it begins with the encryption scheme magic string
       (either "$1$" for MD5-crypt or "$apr1$" for Apache crypt). If so, this is removed. The remaining characters up to the next $ and  up  to  a
       maximum	of  8  characters  are then used as the salt. The salt text should probably be restricted the set of ASCII alphanumeric characters
       plus "./" (dot and forward-slash) - this is to preserve maximum compatability with the unix password file format.

       If a password is being generated rather than checked from a password file then the salt command may be used to generate a random salt.

EXAMPLES

       % md5crypt::md5crypt password 01234567
       $1$01234567$b5lh2mHyD2PdJjFfALlEz1

       % md5crypt::aprcrypt password 01234567
       $apr1$01234567$IXBaQywhAhc0d75ZbaSDp/

       % md5crypt::md5crypt password [md5crypt::salt]
       $1$dFmvyRmO$T.V3OmzqeEf3hqJp2WFcb.
