Example 6 with TSRequest

use of rdpclient.ntlmssp.asn1.TSRequest in project cloudstack by apache.

the class ServerNtlmsspPubKeyPlus1 method handleOneTimeData.

@Override
protected void handleOneTimeData(ByteBuffer buf, Link link) {
    TSRequest tsRequest = new TSRequest("TSRequest");
    tsRequest.readTag(buf);

    if (encryptedPubKey == null || encryptedPubKey.length == 0)
        throw new RuntimeException("[" + this + "] ERROR: Unexpected message from RDP server. Expected encrypted server public key but got nothing instead. Data: " + buf);
    byte[] decryptedPubKey = ntlmState.ntlm_DecryptMessage(encryptedPubKey.toByteArray());
    //* DEBUG */System.out.println("Decrypted pub key:\n" + new ByteBuffer(decryptedPubKey).dump());
    // Decrease first byte by 1
    decryptedPubKey[0]--;
    // Compare returned value with expected value
    if (!Arrays.equals(decryptedPubKey, ntlmState.subjectPublicKey))
        throw new RuntimeException("[" + this + "] ERROR: Unexpected message from RDP server. Expected encrypted server public key but an unknown response. Encryted key after decryption: " + new ByteBuffer(decryptedPubKey).toPlainHexString());
    buf.unref();
