Provide an extension of crypto module to support AES 128 ECB cipher. This erlang module contains NIFs (Native Implemented Function). The encryption algorithm relies on the C openssl libraries, extracted in the folder `libopenssl/`.

## Compilation

User rebar3

	rebar3 compile

## Usage

**Encrypt binary**

	PlainText = <<"Encryption test">>,
	Key = <<16#ab,16#cd,16#ef,16#01,16#23,16#45,16#67,16#89,
			16#bb,16#1b,16#5d,16#17,16#73,16#76,16#9d,16#a2>>,
	CipherText = crypto_ext:block_encrypt(aes_ecb128,Key,PlainText).


**Decrypt binary**

	PlainTextDecoded = crypto_ext:block_decrypt(aes_ecb128,Key,CipherText).
