Examples with TSRequest rdpclient.ntlmssp.asn1.TSRequest used on opensource projects

Example 1 with TSRequest

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

the class ClientNtlmsspNegotiate method onStart.

@Override
protected void onStart() {
    super.onStart();
    ByteBuffer negoToken = generateNegotiateMessage();
    // Store message for MIC calculation in AUTH message
    ntlmState.negotiateMessage = negoToken.toByteArray();
    // Length of packet
    ByteBuffer buf = new ByteBuffer(1024, true);
    TSRequest tsRequest = new TSRequest("TSRequest");
    tsRequest.version.value = 2L;
    NegoItem negoItem = new NegoItem("NegoItem");
    negoItem.negoToken.value = negoToken;
    tsRequest.negoTokens.tags = new Tag[] { negoItem };
    tsRequest.writeTag(buf);
    // Trim buffer to actual length of data written
    buf.trimAtCursor();

        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
