The export version of rpem is also available at kampi.hut.fi
(130.233.224.2) under directory alo.

I also made an interface package (des.c and des.h) which uses my DES
with rpem. This package is in rpem_alodes.tar.Z. My DES is in
des-dist.tar.Z.

By the way, in my opinion, RSA has not been very cooperative in
announcing their claims for RSA. 22 Dec 1989 I sent them
(rsa@well.UUCP) mail stating that I would be willing to put their
notice to my bignum package, especially for US users implementing RSA
with it. Jim Bidzos answered Jan 8 1990 stating that the reply would
be comping by regular mail. It never came.

And please remember, to my knowledge none of these exponentiation
ciphers has any patents outside US.
