VERSION

Version 0.02

SYNOPSIS

use Enterprise::Licence::Generate;
use Enterprise::Licence::Validate;

my $sec = 'ab3yq34s1£f';
my $generator = Enterprise::Licence::Generate->new({ secret => $sec });

my $client = 'unique';
my $licence = $generator->generate($client, { years => 99 });

my $validator = Enterprise::Licence::Validate->new({ secret => $sec });
my @valid = $validator->valid($licence, $client);
# (1) == valid
# (0, 1) == expired
# (0, 0) == invalid

Description

My software is white labeled and distributed into environments that I do not control. I needed a way to programmatically licence code for a set period of time 1 month trial, 5 years etc.

The Licence

The following is an example of a licence that this module generates:

jQT42jKM_-gfPn32-qs49pg-lpsYxqok

It can be broken down into 4 parts:

secret + client/environment
jQT42jKM_

Decimal Huffman compressed secret + Decimal Huffman compressed client/environment bijected.

start time
gfPn32

The Bijected epoch your licence is valid from.

expire time
qs49pg

The Bijected epoch your licence is valid to.

duration
lpsYxqok

The Bijected duration of the licence (expire time - start time) this is to validate that the licence has not been manipulated.

Generate/Validate

new

Both Generate and Validate accept the same parameters to new

secret

A string that should have an entropy greater than 3. This value is meant to be set at application level, hidden in compiled abstracted code.

increment

A float that will be used to build the huffman symbols table.

biject

An array reference that is passed to bijection_set.

offset

An offset that is passed to bijection_set.

generate

To generate a licence it as simple as the following:

my $generator = Enterprise::Licence::Generate->new({ secret => $secret });
my $licence = $generator->generate('world-wide', { months => 1 });
client/environment

The first param to generate should be your environment/client identifier.

duration

The second param should be a valid reference that can be passed to DateTime->add().

validate

To validate a licence:

my $validator = Enterprise::Licence::Validate->new({ secret => $secret });
my @valid = $validator->valid($licence, 'world-wide');
# (1) == The licence is valid
# (0, 1) == The licence is valid but it has expired
# (0, 0) == The licence is invalid.
client/environment

The first param to validate should be the licence string.

duration

The second param to validate should be your environment/client identifier.
