I wanted the speed of rsh or telnet on my 386SX, for connecting over the local network, but I knew that the code was of poor quality compared to ssh, so I patched ssh to add a “none” cipher for unencrypted communication.

SSH with no encryption is popular for high-speed long-distance file transfers in some science disciplines. These large transfers are typically of science sensor output, which for Big Science is random-appearing data until it is crunched by some $millions of supercomputer into a fuzzy pixel. Whilst the data is not encrypted, the sensor output does meet some attributes of encrypted data.

To avoid serious user error, the OpenSSH project won't upstream a 'none' encryption option, so a fork of PortableSSH is maintained at github.com/rapier1/hpn-ssh.
