crypto shell trickery!

I recently imported crash into my github. It features
IP6-ready SSH-like remote shell, using strong public key
authentication and TLS-encrypted transport. It does not
rely on SSL/TLS internal X509 cecking but compares
hostkeys bit-wise. It runs on Linux and embedded derivates,
Android, BSD, Solaris and OSX/Darwin. It does not require root
and has back-connect and trigger modes built in. It can
also be invoked as a CGI.

Update: Pushed a fix into git to use SHA512 rather than
SHA1 for signing authentication requests. That makes
it incompatible with earlier versions. Also fixed a bug
where crashc did not properly distribute SIGWINCH to the
remote peer. Now you can use your ncurses porn and resize
your xterm and it gets properly adjusted! Also tested
authentication RSA keys of up to 7500 bit in size. That
should resist upcoming (TS//SI//REL) QUANTUMFUCK computers.
I need to find the time to enforce cipher-lists and add
ephemeral keying though. (done)
Also good news: crash also integrates with sshttp!
