App::genpw - Generate random password
This document describes version 0.001 of App::genpw (from Perl distribution App-genpw), released on 2018-01-08.
See the included script genpw.
Usage:
genpw(%args) -> [status, msg, result, meta]
Generate random password.
This is yet another utility to generate random password. Features:
Allow specifying pattern(s), e.g. '%8a%s' means 8 random alphanumeric characters followed by a symbol.
Use strong random source (Math::Random::Secure) when available, otherwise fallback to Perl's builtin rand().
rand()
This function is not exported.
Arguments ('*' denotes required arguments):
case => str (default: "default")
Force casing.
default means to not change case. random changes casing some letters randomly to lower-/uppercase. lower forces lower case. upper forces UPPER CASE. title forces Title case.

len => posint
If no pattern is supplied, will generate random alphanum characters with this exact length.
max_len => posint
If no pattern is supplied, will generate random alphanum characters with this maximum length.
min_len => posint
If no pattern is supplied, will generate random alphanum characters with this minimum length.
num => int (default: 1)
patterns => array[str]
Pattern(s) to use.
A pattern is string that is similar to a printf pattern. %P (where P is certain letter signifying a format) will be replaced with some other string. %Nw (where N is a number) will be replaced by a word of length N, %N$MP (where N and M is a number) will be replaced by a word of length between N and M. Anything else will be used as-is. Available conversions:
%l Random Latin letter (A-Z, a-z) %d Random digit (0-9) %a Random letter/digit (Alphanum) (A-Z, a-z, 0-9; combination of %l and %d) %s Random ASCII symbol, e.g. "-" (dash), "_" (underscore), etc. %x Random letter/digit/ASCII symbol (combination of %a and %s) %% A literal percent sign %w Random word
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
