Add LSH, a login program similar to SSH. It depends on SECSH, which does

not require any patent-encumbered encryption algorithms, unlike SSH1, which
depends on RSA, and SSH2, which is not free (of course, these days, this is
not so true thanks to OpenSSH, but it's good to have alternatives!).

+lsh is a client that can connect to the corresponding lshd server.  It uses
+the SECSH protocol, which means that it is compatible with SSH 2.0, except
+for file transfer, which is not part of SECSH.
+
+SECSH uses compression and encryption algorithms that are unencumbered, and
+lsh itself is GPL.
+
+lsh is not as feature-rich as OpenSSH, as it doesn't currently support
+password-protected keyrings, the SSH 1.X protocols, TCP wrappers, etc.
+On the other hand, it doesn't require OpenSSL, and doesn't take a lot of
+work to avoid patented algorithms.

+Port author's notes on usage and common problems can be found at
+WWW: http://gz.geekazoid.com/lsh/
