Perhaps you are looking for Portable OpenSSH or FreeSSH?
OpenSSH is a FREE version of the SSH protocol suite of network
connectivity tools that increasing numbers of people on the Internet
are coming to rely on. Many users of telnet, rlogin, ftp, and other such
programs might not realize that their password is transmitted across
the Internet unencrypted, but it is. OpenSSH encrypts all traffic
(including passwords) to effectively eliminate eavesdropping,
connection hijacking, and other network-level attacks. Additionally,
OpenSSH provides a myriad of secure tunneling capabilities, as well
as a variety of authentication methods.
OpenSSH is an OpenBSD project and *Portable* OpenSSH covers:
AIX, HP-UX, Irix, Linux, NeXT, SCO, SNI/Reliant Unix, Solaris,
Digital Unix/Tru64/OSF, MacOS X, Cygwin and more . . .
There is a fab Windows SSH client called PuTTY which does
excellent terminal emulation and works perfectly with
Midnight Commander. Also Windows GUI front-ends for
the SSH file transfer program.
Likewise SSH clients and servers, for Mac, PalmOS, Java . . .
MSDOS, Windows CE, BEOS, VMS, RISCOS . . .
Apparently ownership of the trademark "SSH" is in dispute,
so not every station in the SSH firmament will help you find
