Russ Magee 39a0890346 Merge branch 'kexsh-proto' of ssh://tripe.blitter.com/~russtopia/git/herradurakex into kexsh-proto 2018-01-20 21:28:55 -08:00
Russ Magee e3842e4219 Removed channel-based server loop goroutine, solving eaten initial byte issue.

constant header/crib exposure, and would add lots of complexity to Read/Write)
TODO: Add CTR, other modes
