data::password
Password(3pm) User Contributed Perl Documentation Password(3pm)
NAME
Data::Password - Perl extension for assesing password quality.
SYNOPSIS
use Data::Password qw(IsBadPassword);
print IsBadPassword("clearant");
# Bad password - contains the word 'clear', only lowercase
use Data::Password qw(:all);
$DICTIONARY = 0;
$GROUPS = 0;
print IsBadPassword("clearant");
DESCRIPTION
This modules checks potential passwords for crackability. It checks that the password is in the appropriate length, that it has enough
character groups, that it does not contain the same chars repeatedly or ascending or descending characters, or charcters close to each
other in the keyboard. It will also attempt to search the ispell word file for existance of whole words. The module's policies can be
modified by changing its variables. (Check "VARIABLES"). For doing it, it is recommended to import the ':all' shortcut when requiring it:
use Data::Password qw(:all);
FUNCTIONS
1. IsBadPassword(password)
Returns undef if the password is ok, or a textual description of the fault if any.
2. IsBadPasswordForUNIX(user, password)
Performs two additional checks: compares the password against the login name and the "comment" (ie, real name) found on the user file.
VARIABLES
1. $DICTIONARY
Minimal length for dictionary words that are not allowed to appear in the password. Set to false to disable dictionary check.
2. $FOLLOWING
Maximal length of characters in a row to allow if the same or following. If $FOLLOWING_KEYBOARD is true (default), the module will
also check for alphabetical keys following, according to the English keyboard layout. Set $FOLLOWING to false to bypass this check.
3. $GROUPS
Groups of characters are lowercase letters, uppercase letters, digits and the rest of the allowed characters. Set $GROUPS to the number
of minimal character groups a password is required to have. Setting to false or to 1 will bypass the check.
4. $MINLEN
$MAXLEN
Minimum and maximum length of a password. Both can be set to false.
5. @DICTIONARIES
Location where we are looking for dictionary files. You may want to set this variable if you are using not *NIX like operating system.
FILES
o /usr/share/dict/web2
o /usr/share/dict/words
o /etc/passwd
SEE ALSO
See Data::Password::BasicCheck if you need only basic password checking.
