Netkey for Plan 9 clients

Netkey is a Plan 9 program that implements an encryption algorithm to allow a remote Plan 9 user to connect securely to a Plan 9 service such as telnet or ftp, without transmitting a password in clear-text form across a network. It replaces the use of a Securenet encryption box. To connect using a non-Plan 9 system, you need either the box, or an implementation of netkey for whatever client system you have got to hand.

Here are references to sources and/or binaries for implementations of netkey's algorithm by various people for non-Plan 9 client systems:
