NAME

Dancer2::Plugin::EncryptID - Obfuscate IDs/string in URLs

VERSION

Version 0.01

DESCRIPTION

This module makes easy to obfuscate internal IDs when using them in a URL given to users. Instead of seeing http://example.com/item/42 users will see http://example.com/item/c98ea08a8e8ad715 . This will prevent nosy users from trying to iterate all items based on a simple ID in the URL.

CONFIGURATION

Configuration requires a secret key at a minimum.

Either put this in your config.yml file:

    plugins:
      EncryptID:
        secret: 'my_secret_password'

Or set the secret key at run time, with:

    BEGIN {
        set plugins => {
            EncryptID => {
                secret => 'abc123xyz',
                padding_character => '!'
            },
        };
    }

SYNOPSIS

    package MyApp;

    use strict;
    use warnings;

    use Dancer2;

    BEGIN { # would usually be in config.yml
        set plugins => {
            EncryptID => {
                secret => 'abc123xyz',
                padding_character => '!'
            },
        };
    }

    use Dancer2::Plugin::EncryptID;

    get '/' => sub {

                # Any ID (numeric or alpha-numeric) you want to obfuscate
                my $someid = int(rand(42)+1);

                my $encoded_id = dancer_encrypt($someid);
                my $url = request->uri_for("/item/$encoded_id");
    };

    get '/item/:encoded_id' => sub {

                # Decode the ID back to clear-text
                my $item_id = dancer_decrypt( params->{encoded_id} ) ;

                return "Showing item '$item_id'";
    };

    1;

SUBROUTINES/METHODS
