Example 1 with CMac

use of org.bouncycastle.crypto.macs.CMac in project openremote by openremote.

the class SecureUtils method calculateCMAC.

public static byte[] calculateCMAC(final byte[] data, final byte[] key) {
    final byte[] cmac = new byte[16];
    CipherParameters cipherParameters = new KeyParameter(key);
    BlockCipher blockCipher = new AESEngine();
    CMac mac = new CMac(blockCipher);
    mac.init(cipherParameters);
    mac.update(data, 0, data.length);
    mac.doFinal(cmac, 0);
    return cmac;
