App::genpw - Generate random password (support patterns + wordlists)
This document describes version 0.007 of App::genpw (from Perl distribution App-genpw), released on 2018-05-01.
See the included script genpw.
Usage:
genpw(%args) -> [status, msg, result, meta]
Generate random password (support patterns + wordlists).
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 words from wordlists.
Use strong random source (Math::Random::Secure) when available, otherwise fallback to Perl's builtin rand().
rand()
Examples:
By default generate letters/digits 8-20 characters long:
% genpw J9K3ZjBVR
Generate 5 passwords instead of 1:
% genpw 5 wAYftKsS knaY7MOBbcvFFS3L1wyW oQGz62aF sG1A9reVOe Zo8GoFEq
Generate random digits between 10 and 12 characters long:
% genpw -p '%10$12d' 55597085674
Generate password in the form of a random word + 4 random digits. Words will be fed from STDIN:
% genpw -p '%w%4d' < /usr/share/dict/words shafted0412
Like the above, but words will be fetched from WordList::* modules. You need to install the genpw-wordlist CLI. By default, will use wordlist from WordList::EN::Enable:
WordList::*
% genpw-wordlist -p '%w%4d' sedimentologists8542
Generate a random GUID:
% genpw -p '%8h-%4h-%4h-%4h-%12h' ff26d142-37a8-ecdf-c7f6-8b6ae7b27695
Like the above, but in uppercase:
% genpw -p '%8h-%4h-%4h-%4h-%12h' 22E13D9E-1187-CD95-1D05-2B92A09E740D
Use configuration file to avoid typing the pattern every time, put this in ~/genpw.conf:
~/genpw.conf
[profile=guid] patterns = "%8h-%4h-%4h-%4h-%12h"
then:
% genpw -P guid 008869fa-177e-3a46-24d6-0900a00e56d5
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.
default
random
lower

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) %h Random hexdigit (0-9a-f) %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) %m Base64 character (A-Z, a-z, 0-9, +, /) %b Base58 character (A-Z, a-z, 0-9 minus IOl0) %B Base56 character (A-Z, a-z, 0-9 minus IOol01) %% 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)
