Example 6 with PKCS12PBEParams

use of org.bouncycastle.asn1.pkcs.PKCS12PBEParams in project XobotOS by xamarin.

the class JDKPKCS12KeyStore method cryptData.

protected byte[] cryptData(boolean forEncryption, AlgorithmIdentifier algId, char[] password, boolean wrongPKCS12Zero, byte[] data) throws IOException {
    String algorithm = algId.getObjectId().getId();

    PBEKeySpec pbeSpec = new PBEKeySpec(password);
    try {
        SecretKeyFactory keyFact = SecretKeyFactory.getInstance(algorithm, bcProvider);
        PBEParameterSpec defParams = new PBEParameterSpec(pbeParams.getIV(), pbeParams.getIterations().intValue());
        JCEPBEKey key = (JCEPBEKey) keyFact.generateSecret(pbeSpec);
