# Authenticated-Encryption
A implementation of Authenticated Encryption
## Usage
Encrypt
“‘
(aead::authenticated-encrypt plain-text-as-bytes :secret secret-bytes)
;=> encrypted-bytes
“‘
Decrypt
“‘
(aead::authenticated-decrypt encrypted-bytes :secret secret-bytes)
;=> plain-text-as-bytes
; or raise authenticated-decrypt-error condition
“‘

Decrypt message with secret key
ENCRYPTED and SECRET must be array of (unsigned-byte 8).
Returns the decrypted bytes.
Conditions:
authenticated-decrypt-error when invalid encrypted bytes
Encrypt the message with secret key
MESSAGE and SECRET must be array of (unsigned-byte 8).
NONCE will generate per evaluate if nil (default).
CIPHER-NAME accepts only :AES (default) for now.
Returns the encrypted bytes.
Encrypted Bytes Format are:
Header (2 byte) +
Nonce (16 byte) +
Encrypted Message (with PKCS#7 padding) +
Tag (16 byte)
(16 = AES block size)
simple-error.
