NAME

App::GoogleAuthUtils - Utilities related to Google Authenticator

VERSION

This document describes version 0.006 of App::GoogleAuthUtils (from Perl distribution App-GoogleAuthUtils), released on 2024-04-18.

DESCRIPTION

This distributions provides the following command-line utilities:

FUNCTIONS

gen_google_auth_qrcode

Usage:

 gen_google_auth_qrcode(%args) -> [$status_code, $reason, $payload, \%result_meta]

Generate Google authenticator QR code (barcode) from a secret key.

Examples:

  • Example #1:

     gen_google_auth_qrcode(
   secret_key => "6XDT6TSOGR5SCWKHXZ4DFBRXJVZGAKAW",
   issuer => "example.com"
 );

When generating a new 2FA token, you are usually presented with a secret key as well as a 2D barcode (QR code) representation of this secret key. You are advised to store the secret key and it's usually more convenient to store the key code instead of the QR code. But when entering the secret key to the Google authenticator app, it's often more convenient to scan the barcode instead of typing or copy-pasting the code.

This utility will convert the secret key code into bar code (opened in a browser) so you can conveniently scan the bar code into your app.

This function is not exported.

Arguments ('*' denotes required arguments):

  • account => str

    (No description)

  • issuer* => str

    (No description)

  • output => filename

    (No description)

  • secret_key* => str

    (No description)

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.

Return value: (any)

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.
