Example 6 with HMac

use of org.bouncycastle.crypto.macs.HMac in project XobotOS by xamarin.

the class JDKKeyStore method engineStore.

public void engineStore(OutputStream stream, char[] password) throws IOException {
    DataOutputStream dOut = new DataOutputStream(stream);
    byte[] salt = new byte[STORE_SALT_SIZE];
    int iterationCount = MIN_ITERATIONS + (random.nextInt() & 0x3ff);
    random.nextBytes(salt);
    dOut.writeInt(STORE_VERSION);
    dOut.writeInt(salt.length);
    dOut.write(salt);
    dOut.writeInt(iterationCount);
    // BEGIN android-changed
    HMac hMac = new HMac(new OpenSSLDigest.SHA1());
    MacOutputStream mOut = new MacOutputStream(dOut, hMac);
    PBEParametersGenerator pbeGen = new PKCS12ParametersGenerator(new OpenSSLDigest.SHA1());
    // END android-changed
    byte[] passKey = PBEParametersGenerator.PKCS12PasswordToBytes(password);
    pbeGen.init(passKey, salt, iterationCount);
    hMac.init(pbeGen.generateDerivedMacParameters(hMac.getMacSize()));
    for (int i = 0; i != passKey.length; i++) {
        passKey[i] = 0;
    }
    saveStore(mOut);
    byte[] mac = new byte[hMac.getMacSize()];
    hMac.doFinal(mac, 0);
    dOut.write(mac);
    dOut.close();
}
