A pure Node.js implementation of the AES-CMAC algorithm per NIST Special Publication 800-38B and (RFC 4493). This algorithm creates a cryptographic message authentication code (CMAC) from a given message using the AES cipher with 128, 192, and 256 bit keys.
At work we had a need to run AES-CMAC from Node.js. A coworker created an implementation which uses a C++ addon which wrapped Crypto++, but unfortunately the module was only known to build correctly on Ubuntu. OS X support was added through some further hacking, but Windows support was extremely difficult.
Searching the web yielded no alternatives, so I started this project with a goal to create an AES-CMAC implementation to share with the Node.js community which would be easy to use on OS X, Windows, and Linux.
Currently the project only uses the built-in cryptographic functions provided by Node.js and avoids using C/C++ addons. This was a conscious trade-off favoring simplicity over raw performance.
npm install node-aes-cmac
The module exposes a single method: aesCmac(key, message[, options])
key
- (string
| Buffer
) the cryptographic key to use for the operation.
Must be 128, 192, or 256 bits in length.message
- (string
| Buffer
) the message.options
- (object
optional) a set of extra options to pass into the method:
returnAsBuffer
- (boolean
) set to true
to get the returned CMAC as a Buffer
instead of a string. Defaults to false
.The method normally returns the CMAC as a lowercase hexadecimal string
.
It can also return a Buffer
if the returnAsBuffer
option is set to true
.
