node-aes-ccm

AES CCM module for io.js using OpenSSL

Installation

npm install node-aes-ccm

node-aes-ccm requires io.js >= 3.0 because we need OpenSSL 1.0.2d or later for AES CCM support.

encrypt(key, iv, plaintext, aad, auth_tag_length)

key, iv, plaintext, and aad are all Buffer objects. encrypt will return an object like the following:

{
  ciphertext: Buffer,
  auth_tag: Buffer
}

decrypt(key, iv, ciphertext, aad, auth_tag)

key, iv, plaintext, aad, and auth_tag are all Buffer objects. decrypt will return an object like the following:

{
  plaintext: Buffer,
  auth_ok: Boolean
}

Modeled after node-aes-gcm.
