String::MkPasswd(3pm) User Contributed Perl Documentation String::MkPasswd(3pm)NAMEString::MkPasswd - random password generatorSYNOPSISuse 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, );ABSTRACTThis 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.DESCRIPTIONThe 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. -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.SEE ALSO<http://expect.nist.gov/#examples>, mkpasswd(1)AKNOWLEDGEMENTSDon Libes of the National Institute of Standards and Technology, who wrote the Expect example, mkpasswd(1).AUTHORChris Grau <cgrau@cpan.org>COPYRIGHT AND LICENSECopyright (C) 2003-2010 by Chris Grau This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself, either Perl version 5.8.1 or, at your option, any later version of Perl 5 you may have available. perl v5.10.1 2010-10-18 String::MkPasswd(3pm)
