String::MkPasswd - random password generator
use String::MkPasswd qw(mkpasswd); print mkpasswd(); # for the masochisticly paranoid... print mkpasswd( -length => 27, -minnum => 5, -minlower => 1, # minlower is increased if necessary -minupper => 5, -minspecial => 5, -distribute => 1, );
This Perl library defines a single function, "mkpasswd()", to generate random passwords. The function is meant to be a simple way for developers and system administrators to easily generate a relatively secure password.
The exportable "mkpasswd()" function returns a single scalar: a random password. By default, this password is nine characters long with a random distribution of four lower- case characters, two upper-case characters, two digits, and one non-alphanumeric character. These parameters can be tuned by the user, as described in the "ARGUMENTS" section. ARGUMENTS The "mkpasswd()" function takes an optional hash of arguments. -length The total length of the password. The default is 9. -minnum The minimum number of digits that will appear in the final password. The default is 2. -minlower The minimum number of lower-case characters that will appear in the final password. The default is 2. -minupper The minimum number of upper-case characters that will appear in the final password. The default is 2. -minspecial The minimum number of non-alphanumeric characters that will appear in the final password. The default is 1. -distribute If set to a true value, password characters will be distributed between the left- and right-hand sides of the keyboard. This makes it more difficult for an onlooker to see the password as it is typed. The default is false. -noambiguous If set to a true value, password characters will not include any that might be mistaken for others. This is particularly helpful if you're distributing a printed list of passwords to a group of people. The default is false. -fatal If set to a true value, "mkpasswd()" will Carp::croak() rather than return "undef" on error. The default is false. If -minnum, -minlower, -minupper, and -minspecial do not add up to -length, -minlower will be increased to compensate. However, if -minnum, -minlower, -minupper, and -minspecial add up to more than -length, then "mkpasswd()" will return "undef". See the section entitled "EXCEPTION HANDLING" for how to change this behavior. EXCEPTION HANDLING By default, "mkpasswd()" will return "undef" if it cannot generate a password. Some people are inclined to exception handling, so String::MkPasswd does its best to accommodate them. If the variable $String::MkPasswd::FATAL is set to a true value, "mkpasswd()" will Carp::croak() with an error instead of returning "undef". EXPORT None by default. The "mkpasswd()" method is exportable.
