Easy RSA encryption/decryption in Elixir

========================================

This module wraps Erlang's `public_key` module, making RSA encryption/decryption a trivial task.

```elixir

# Decode your public and private keys

public_key = RSA.decode_key "-----BEGIN RSA PUBLIC KEY----- ..."

private_key = ...

# Encrypt a string using the public key and decrypt it using the private key

plaintext = "hello world"

cyphertext = plaintext |> RSA.encrypt {:public, public_key}

# << ... encrypted binary data ... >>

# Encode it to base64

encrypted_b64 = :base64.encode_to_string cyphertext

# "... base64 ASCII text ..."

# Decode a base64 encrypted string and decrypt it

cyphertext = :base64.decode encrypted_b64

plaintext = cyphertext |> RSA.decrypt {:private, private_key}

# "hello world"

```
