Function CMAC

CMAC(key: Buffer, message: Buffer): Buffer

CMAC algorithm, nodejs default crypto module does not support CMAC, so we need to implement it ourselves.

Parameters

key: Buffer
key must be 128, 192, or 256 bits in length.
message: Buffer
input message

Returns Buffer

CMAC result

Example

const key=Buffer.from('2b7e151628aed2a6abf7158809cf4f3c','hex');
const message=Buffer.from('6bc1bee22e409f96e93d7e117393172a','hex');
const result=CMAC(key,message);
//which should print 070a16b46b4d4144f79bdd9dd04a287c
console.log(result.toString('hex'));
