When using a NULL cipher it's really useful to have a non-random pattern for the payload so you can see, e.g. in packet captures, the payload bytes. In its final form, we are not using a NULL cipher, but the ability to switch between random and non-random content is useful for troubleshooting. -- This is an automated message from the Apache Git Service.
