public static void main(String[] args) throws IOException {
    byte[] pkBytes = readBinaryFile(
            "/home/tsenger/Dokumente/Programming/animamea/certs/Key_DEATTIDBSIDE003.pkcs8");

    DERSequence pkSeq = (DERSequence) DERSequence.fromByteArray(pkBytes);

    PrivateKeyInfo pkInfo = new PrivateKeyInfo(pkSeq);

    AlgorithmIdentifier ecPublicKey = pkInfo.getPrivateKeyAlgorithm();
    System.out.println(ecPublicKey.getAlgorithm().toString());
    System.out.println(HexString.bufferToHex(ecPublicKey.getEncoded(null)));

    X9ECParameters ecp = X9ECParameters.getInstance(ecPublicKey.getParameters());

    System.out.println("N: \n" + HexString.bufferToHex(Converter.bigIntToByteArray(ecp.getN())));

    ECPrivateKey ecpk2 = ECPrivateKey.getInstance(ecPublicKey);
    //ECPrivateKey.getInstance(pkInfo.getPrivateKey());
    System.out.println("private Key: \n" + HexString.bufferToHex(Converter.bigIntToByteArray(ecpk2.getKey())));
