MIT-PGP is for U. S. and Canadian use only, but MIT is only distributing it within the USA (due to some archaic export control laws).

My public key is available from both of the above services.

Send email to pgp-public-keys@pgp.mit.edu with a subject of "get mpj8" to get my key from a free key server.

For commercial use, use Viacrypt PGP, which is fully licensed to use both the RSA and IDEA algorithms in commercial and corporate environments (as well as personal use, of course).
Another restriction is due to an exclusive marketing agreement between Philip Zimmermann and Viacrypt that applies to the USA and Canada only. Viacrypt has exclusive rights to market PGP commercialy in this area of the world. This means that if you want to market PGP commercially in competition with Viacrypt in the USA or Canada, you would have to create a new implementation of the functions of PGP containing none of Philip Zimmermann's copyrighted code. You are free to modify existing PGP code for your own use, as long as you don't sell it. Phil would also appreciate your checking with him before you distribute any modified versions of PGP as freeware.
"PGP", "Pretty Good Privacy" and "Phil's Pretty Good Software" are trademarks owned by Philip Zimmermann. This means that if you modify an older version of PGP that was issued under the copyleft license and distribute it without Phil's permission, you have to call it something else. This avoids confusing all of us and protects Phil's good name.
For commercial use, use Viacrypt PGP, which is fully licensed to use the IDEA algorithm in commercial and corporate environments.
The exclusive marketing agreement with Viacrypt also applies in Canada. See the section on USA intellectual property restrictions for more details.
The IDEA conventional block cipher is covered by US Patent 5,214,703 and European patent EP 0 482 154 B1. IDEA is a trademark of Ascom-Tech AG. Commercial users of IDEA (including commercial use of PGP) may obtain licensing details from Ph. Baumann, Ascom Tech Ltd., IDEA Lizenz, Postfach 151, CH-4502 Solothurn, Switzerland, Tel ++41 65 242828, Fax ++41 65 242847.
If you are just encrypting love letters or other personal mail (for which you don't get paid) on your own personal computer, that is not commercial. If you are encrypting official business mail on your for-profit corporation's computer with PGP, that is commercial use.
Note that there are some gray areas not covered above, and the patent owners of RSA and IDEA may differ from my interpretation in the areas not covered above, so if you are in doubt, you should consider the licensing of Viacrypt PGP (or outside of North America, direct licensing of IDEA) to be cheap legal insurance. Indeed, the license fee is probably a lot cheaper than a legal opinion from a lawyer qualified to make such a judgement. Note that I am not a lawyer and the above is not legal advice. Use it at your own risk.

There are many other frequently asked questions. Most of them are covered in the documentation that comes with PGP, and the few that aren't are addressed in documents referenced above.
