- * we disable the check for valid client signatures, then we see that
- * the output of a rpcecho 'sinkdata' at smbd is correct. We get the
- * valid data, and it is validly decrypted.
- *
- * This means that the quantity of data passing though the RC4 sealing
- * pad is correct.
- *
- * This code also correctly matches test values that I have obtained,
- * claiming to be the correct output of NTLM2 signature generation.
+ * NTLM2 is a AEAD system. This means that the data encrypted is not
+ * all the data that is signed. In DCE-RPC case, the headers of the
+ * DCE-RPC packets are also signed. This prevents some of the
+ * fun-and-games one might have by changing them.
