This program should use the Diffie-Helman algorithm for public key
encryption, not the RSA algorithm, because the Diffie-Helman patent in
the US will expire in 1997. It should use triple-DES, not IDEA, for
block encryption because IDEA is patented in many countries and the
block encryption, because IDEA is patented in many countries and the
patents will not expire soon. In other respects, it should be like PGP.
This program needs to be written by someone who is not a US citizen,
outside the US, to avoid problems with US export control law.
Many people believe that PGP is free software, but that is not actually
true. The distribution terms set by the copyright holders do not allow
everyone to use and redistribute it.
true. The distribution terms do not allow everyone to use and
redistribute it. We used to think that these restrictions had been
imposed by the patent holders for the RSA and IDEA algorithms, and that
PGP could be free software if these algorithms were replaced by
alternatives. But we have since learned that the owners of PGP are
themselves unwilling to make it free software. Writing a new program is
the only way to get free software for this job.

A free secure telnet program more or less like ssh/sshd. Since this
requires a public key encryption algorithm, it is closely related to the
preceding item.
This program should follow the draft standard for ssh. As always, it
cannot implement the RSA algorithm, but must instead support the
alternatives that will be patent-free in late 1997. It cannot support
IDEA, but can use triple-DES and some other alternatives.
