Obfuscates 32-bit numbers.

Transform your internal ids to obfuscated integers. Similar to Hashids, although around 1000x faster (see the priv/benchmark/benchmark.exs).

Elixir implementation is compatible with PHP implementation.

Usage

In order to encode/decode anything, you'll first have to fetch yourself the OptimusId.Secret tuple. That's the mystic 2nd argument to encode/2 and decode/2 that you'll see in the examples below.

Now, let's start by encoding:

iex> OptimusId.encode(17, {2078493839, 1968460399, 2327522479})
2963487184

Our internal identifier (17) was transformed into obfuscated identifier (2963487184) which is safe to be made public.

In order to recover original identifier we have to call decode function:

iex> OptimusId.decode(2963487184, {2078493839, 1968460399, 2327522479})
17
