I think again this was done to make a free speech argument challenging
the regulations moot so that they could still harrass companies when needed.

One other note is that the original version of PGP used the IDEA encryption algorithm. This algorithm is covered by a patent for a couple of years yet. So the supplied version of gpg in many distros is not going to be able to handle stuff ecnrypted with the original gpg and some old keys. This probably
won't be a problem for you.

To make a long story short, some of the technology behind public key encryption is based on a patent owned by MIT and leased to RSA. The technology was developed by Ronald Rivest, Adi Shamir, and Leonard Adleman who were at MIT at the time although public key encryption was originally proposed at Stanford. There was a big battle waged between RSA and Phil Zimmerman, and during that time, MIT was able to open source some of the technology. I'm being very general, because that was the subject of last December's Boston Linux and Unix meeting which we hold at MIT each month.

AFAIK the patent expired last year...

Yes it did.
