Elixir library for generating tripcodes.

From the full wiki:

A tripcode is a means of telecommunication authentication that does not require registration. Tripcodes are most often used in 2channel-style message boards or Futaba Channel-style imageboards. A tripcode is a hashed password by which a person can be identified by others.

Note: There exist widely different implementations of tripcodes, this one is based on https://github.com/justinjensen/tripcode/

The package can be installed by adding ex_tripcode to your list of dependencies in mix.exs:

def deps do
  [
    {:ex_tripcode, "~> 1.0"},
  ]
end

https://hexdocs.pm/ex_tripcode/ExTripcode.html

Most simple usage:

iex> ExTripcode.hash("elixir")
"H3R1pplX/."

Secure Tripcodes work too, just pass in a secret seed:

iex> ExTripcode.hash("elixir", "secret")
"KZ1B7o9AtcJD9XQ"

You can also parse a user string straight away. Note that if you don't pass a seed, it will only parse for regular tripcodes, not secure tripcodes.

iex> seed = "secret"
iex> ExTripcode.parse("User#elixir#elixir", seed)
%{user: "User", code: "H3R1pplX/.", secure: "KZ1B7o9AtcJD9XQ"}

iex> ExTripcode.parse("User##elixir", seed)
%{user: "User", secure: "KZ1B7o9AtcJD9XQ"}

iex> ExTripcode.parse("User#elixir", seed)
%{user: "User", code: "H3R1pplX/."}

iex> ExTripcode.parse("User#elixir")
%{user: "User", code: "H3R1pplX/."}
