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).
