## Dependencies

### Elixir platform
- Elixir 1.7.3
- Erlang/OTP 21

### Supported Databases
Only PostgreSQL with [Postgrex](https://github.com/elixir-ecto/postgrex) is supported at this time, as no abstractions has been implemented (yet) to easily swap between DBs and drivers.

### Supported encryption

As of now, the server provides ECDSA-like signed JWS. A little more development may be necessary to support more algorithms.
