- I even have a partial list:
-
- US Patent Canadian Patent
- 4200770 1121480 (6 April 1982) Hellman-Diffie-Merkle
- 4218582 1128159 (20 July 1982)

- Note that I'm not saying that these patents do apply or that they
- don't apply to PGP. I'm certainly not qualified to even venture
- an informed opinion either way. Note that neither of the above
- is the famous RSA patent.
-
- Personally, I'm going to stick with RIPEM until I know more.
- RIPEM seems to be a "safer" alternative and it is now generally
- available in Canada and the U.S.A.
-
- I'd certainly like to know more about the situation in Canada.
