NAME App::genpw - (Gen)erate random password/strings, with (p)atterns and (w)ordlists VERSION This document describes version 0.013 of App::genpw (from Perl distribution App-genpw), released on 2024-01-16. SYNOPSIS See the included script genpw. FUNCTIONS genpw Usage: genpw(%args) -> [$status_code, $reason, $payload, \%result_meta] (Gen)erate random password/strings, with (p)atterns and (w)ordlists. 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 when available, otherwise fallback to Perl's builtin rand(). Examples: By default generate base56 password 12-20 characters long (-p %12$20B): % genpw Uk7Zim6pZeMTZQUyaM Generate 5 passwords instead of 1: % genpw 5 igYiRhUb5t9d9f3J b7D44pnxZHJGQzDy2eg RXDtqjMvp2hNAdQ Xz3DmAL94akqtZ5xb 7TfANv9yxAaMGXm 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: % genpw -p '%(wordlist:EN::Enable)w%4d' % 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 '%(u)8h-%(u)4h-%(u)4h-%(u)4h-%(u)12h' CA333840-6132-33A1-9C31-F2FF20EDB3EA % genpw -p '%()(Str::uc)8h-%()(Str::uc)4h-%()(Str::uc)4h-%()(Str::uc)4h-%()(Str::uc)12h' CA333840-6132-33A1-9C31-F2FF20EDB3EA % genpw -p '%8h-%4h-%4h-%4h-%12h' -U 22E13D9E-1187-CD95-1D05-2B92A09E740D Use configuration file to avoid typing the pattern every time, put this in "~/genpw.conf": [profile=guid] patterns = "%8h-%4h-%4h-%4h-%12h" then: % genpw -P guid 008869fa-177e-3a46-24d6-0900a00e56d5 Keywords: generate, pattern, wordlist This function is not exported. Arguments ('*' denotes required arguments): * action => *str* (default: "gen") (No description) * 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) (No description) * patterns => *array[str]* Pattern(s) to use. CONVERSION (%P). A pattern is string that is roughly similar to a printf pattern: %P where "P" is certain letter signifying a conversion. This will be replaced with some other string according to the conversion. An example is the %h conversion which will be replaced with hexdigit. LENGTH (%NP). A non-negative integer ("N") can be specified before the conversion to signify desired length, for example, %4w will return a random word of length 4. MINIMUM AND MAXIMUM LENGTH ("%M$NP"). If two non-negative integers separated by "$" is specified before the conversion, this specify desired minimum and maximum length. For example, "%4$10h" will be replaced with between 4 and 10 hexdigits. ARGUMENT AND FILTERS ("%(arg)P", "%(arg)(filter1)(...)P"). Finally, an argument followed by zero or more filters can be specified (before the lengths) and before the conversion. For example, "%(wordlist:ID::KBBI)w" will be replaced by a random word from the wordlist WordList::ID::KBBI. Another example, "%()(Str::uc)4$10h" will be replaced by between 4-10 uppercase hexdigits, and "%(arraydata:Sample::DeNiro)(Str::underscore_non_latin_alphanums)(St r::lc)(Str::ucfirst)w" will be replaced with a random movie title of Robert De Niro, where symbols are replaced with underscore then the string will be converted into lowercase and the first character uppercased, e.g. "Dear_america_letters_home_from_vietnam". Anything else will be left as-is. Available conversions: %l Random Latin letter (A-Z, a-z) %d Random digit (0-9) %h Random hexdigit (0-9a-f in lowercase [default] or 0-9A-F in uppercase). Known arguments: - "u" (to use the uppercase instead of the default lowercase digits) %a Random letter/digit (Alphanum) (A-Z, a-z, 0-9; combination of %l and %d) %s Random ASCII symbol, e.g. "-" (dash), "_" (underscore), etc. %x Random letter/digit/ASCII symbol (combination of %a and %s) %m Base64 character (A-Z, a-z, 0-9, +, /) %b Base58 character (A-Z, a-z, 0-9 minus IOl0) %B Base56 character (A-Z, a-z, 0-9 minus IOol01) %% A literal percent sign %w Random word. Known arguments: - "stdin:" (for getting the words from stdin, the default) - "wordlist:NAME" (for getting the words from a L module) - "arraydata:NAME" (for getting the words from an L module, the Role::TinyCommons::Collection::PickItems::RandomPos will be applied). Filters are modules in the "Data::Sah::Filter::perl::" namespace. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

AUTHOR perlancar CONTRIBUTING To contribute, you can send patches by email/via RT, or send pull requests on GitHub. Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2024, 2020, 2018 by perlancar .
