This may be stupid and is definitely editorial, but should we provide advice for an endpoint to not do the following: CID for connection 1: 0x34a3f036 CID for connection 2: 0x34a3f036a2 ? It would be crazy to do this intentionally, but if an endpoint randomly generates CIDs with differing lengths, it probably ought to catch the case, or otherwise implement trial decryption. -- You are receiving this because you are subscribed to this thread.
