Htpasswd(3) User Contributed Perl Documentation Htpasswd(3)NAMEApache::Htpasswd - Manage Unix crypt-style password file.
SYNOPSIS
use Apache::Htpasswd;
$foo = new Apache::Htpasswd("path-to-file");
$foo = new Apache::Htpasswd({passwdFile => "path-to-file",
ReadOnly => 1}
);
# Add an entry
$foo->htpasswd("zog", "password");
# Change a password
$foo->htpasswd("zog", "new-password", "old-password");
# Change a password without checking against old password
$foo->htpasswd("zog", "new-password", {'overwrite' => 1});
# Check that a password is correct
$foo->htCheckPassword("zog", "password");
# Fetch an encrypted password
$foo->fetchPass("foo");
# Delete entry
$foo->htDelete("foo");
# If something fails, check error
$foo->error;
# Write in the extra info field
$foo->writeInfo("login", "info");
# Get extra info field for a user
$foo->fetchInfo("login");
DESCRIPTION
This module comes with a set of methods to use with htaccess password
files. These files (and htaccess) are used to do Basic Authentication
on a web server.
The passwords file is a flat-file with login name and their associated
crypted password. You can use this for non-Apache files if you wish,
but it was written specifically for .htaccess style files.
FUNCTIONS
Apache::Htpasswd->new(...);
As of version 1.5.4 named params have been added, and it is
suggested that you use them from here on out.
Apache::Htpasswd->new("path-to-file");
"path-to-file" should be the path and name of the file containing
the login/password information.
Apache::Htpasswd->new({passwdFile => "path-to-file",
ReadOnly => 1,
UseMD5 => 1,
});
This is the prefered way to instantiate an object. The 'ReadOnly'
param is optional, and will open the file in read-only mode if
used. The 'UseMD5' is also optional: it will force MD5 password
under Unix.
If you want to support plain un-encrypted passwords, then you need
to set the UsePlain option (this is NOT recommended, but might be
necesary in some situations)
error;
If a method returns an error, or a method fails, the error can be
retrieved by calling error()
htCheckPassword("login", "password");
Finds if the password is valid for the given login.
Returns 1 if passes. Returns 0 if fails.
htpasswd("login", "password");
This will add a new user to the password file. Returns 1 if
succeeds. Returns undef on failure.
htDelete("login")
Delete users entry in password file.
Returns 1 on success Returns undef on failure.
htpasswd("login", "new-password", "old-password");
If the old-password matches the login's password, then it will
replace it with new-password. If the old-password is not correct,
will return 0.
htpasswd("login", "new-password", {'overwrite' => 1});
Will replace the password for the login. This will force the
password to be changed. It does no verification of old-passwords.
Returns 1 if succeeds Returns undef if fails
fetchPass("login");
Returns encrypted password if succeeds. Returns 0 if login is
invalid. Returns undef otherwise.
fetchInfo("login");
Returns additional information if succeeds. Returns 0 if login is
invalid. Returns undef otherwise.
fetchUsers();
Will return either a list of all the user names, or a count of all
the users.
The following will return a list: my @users =
$Htpasswd->fetchUsers();
The following will return the count: my $user_count =
$Htpasswd->fetchUsers();
writeInfo("login", "info");
Will replace the additional information for the login. Returns 0
if login is invalid. Returns undef otherwise.
CryptPasswd("password", "salt");
Will return an encrypted password using 'crypt'. If salt is
ommitted, a salt will be created.
INSTALLATION
You install Apache::Htpasswd, as you would install any perl module
library, by running these commands:
perl Makefile.PL
make
make test
make install
make clean
If you are going to use MD5 encrypted passwords, you need to install
Crypt::PasswdMD5.
If you need to support SHA1 encrypted passwords, you need to install
Digest::SHA1 and MIME::Base64.
DOCUMENTATION
POD style documentation is included in the module. These are normally
converted to manual pages and installed as part of the "make install"
process. You should also be able to use the 'perldoc' utility to
extract and read documentation from the module files directly.
AVAILABILITY
The latest version of Apache::Htpasswd should always be available from:
$CPAN/modules/by-authors/id/K/KM/KMELTZ/

CHANGES
Revision 1.8.0 Added proper PREREQ_PM
Revision 1.7.0 Handle SHA1 and plaintext. Also change the interface
for allowing change of password without first checking old password. IF
YOU DON'T READ THE DOCS AND SEE I DID THIS DON'T EMAIL ME!
Revision 1.6.0 Handle Blowfish hashes when that's the mechanism
crypt() uses.
Revision 1.5.9 MD5 for *nix with new UseMD5 arg for new()
Revision 1.5.8 Bugfix to htpasswd().
Revision 1.5.7 MD5 for Windows, and other minor changes.
Revision 1.5.6 Minor enhancements.
Revision 1.5.5 2002/08/14 11:27:05 Newline issue fixed for certain
conditions.
Revision 1.5.4 2002/07/26 12:17:43 kevin doc fixes, new fetchUsers
method, new ReadOnly option, named params for new(), various others
Revision 1.5.3 2001/05/02 08:21:18 kevin Minor bugfix
Revision 1.5.2 2001/04/03 09:14:57 kevin Really fixed newline problem

Revision 1.3 2000/04/04 15:00:15 meltzek Made file locking safer to
avoid race conditions. Fixed typo in docs.
Revision 1.2 1999/01/28 22:43:45 meltzek Added slightly more verbose
error croaks. Made sure error from htCheckPassword is only called when
called directly, and not by $self.
Revision 1.1 1998/10/22 03:12:08 meltzek Slightly changed how files
