GSSENCRequest (F)Framing and repetition
The complete definition below retains repetition, counts and conditional fields. A numbered table row is a documented field definition, not a fixed byte offset. Integer encodings and flow rules follow the same-version protocol chapter.
Wire fields in documented order
| Position | Format | Meaning |
|---|---|---|
| 1 | Int32(8) | Length of message contents in bytes, including self. |
| 2 | Int32(80877104) | The GSSAPI Encryption request code. The value is chosen to contain 1234 in the most significant 16 bits, and 5680 in the least significant 16 bits. (To avoid confusion, this code must not be the same as any protocol version number.) |
