4.2.2.4 GSS_WrapEx Examples

The GSS_WrapEx() is specified in section 3.4.6. The following data is part of the security context state for the NTLM Session.

SeqNum for the message:

 0000000: 00 00 00 00                                       ••••

RandomPad(4):

 0000000: 00 00 00 00                                       ••••

Plaintext data where conf_req_flag == TRUE and sign == TRUE:

 0000000: 50 00 6c 00 61 00 69 00 6e 00 74 00 65 00 78 00   P·l·a·i·n·t·e·x·
 0000010: 74 00                                             t·

The output message data and signature is created using SEAL() specified in section 3.4.3. Output_message will contain conf_state == TRUE, signed == TRUE and data:
