Ahurt$./mkpasswd -h Usage of mkpasswd: -hash string Optional hash argument: sha512, sha256, md5 or apr1 (default 'sha512') -password string Optional password argument -rounds int Optional number of rounds -salt string Optional salt argument without prefix. The mkpasswd generates indexes over certain security files. These indexes are used by the getpwnam, getpwuid, getuserattr, and putuserattr library subroutines. This approach significantly enhances performance for large user base systems.
- DESCRIPTION
String::MkPasswd - random password generator
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.
The total length of the password. The default is 9.
Linux Mkpasswd
The minimum number of digits that will appear in the final password. The default is 2.
Mkpasswd Windows
The minimum number of lower-case characters that will appear in the final password. The default is 2.
The minimum number of upper-case characters that will appear in the final password. The default is 2.
The minimum number of non-alphanumeric characters that will appear in the final password. The default is 1.
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.
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.
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
Mkpasswd Centos
None by default. The mkpasswd() method is exportable.
