This library should use the Diffie-Helman algorithm for public key

-A free program for sended encrypted mail using public-key encryption.
-
-This program should use the library described above for the public-key
-encryption. It should use triple-DES, not IDEA, for block encryption,
-because IDEA is patented in many countries and the patents will not
-expire soon.
-
-In other respects, it should be like PGP. If the new version of PGP
-no longer uses RSA and IDEA, compatibility with it may be feasible.
-
-There is a suggestion that the Blowfish algorithm might be a good choice
-for the non-public-key block encryption. I'm not an encryption expert
-so I don't have an opinion about that.
-
-Many people believe that PGP is free software, but that is not actually
-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 simple PC BIOS. On most new PCs, the BIOS is stored in writable

+free system on these PCs, we need a free BIOS.
+
+This task is made simpler by the fact that this BIOS need only support
+enough features to enable a boot-loader such as LILO or GRUB to finish
+loading the kernel. Neither Linux nor Mach actually uses the BIOS once
+it starts up. Also, it is not absolutely necessary to do all the many
