- Yes, but there are other possibilities. First, the two people may be able
- to FIND a secure channel, but it is inefficient, expensive, or there is
- some other reason that it can't be used often. This method can be used to
- transfer keys and then RSA used over unsecure channels from then on.
- Second, both parties can have secure channels with a third party. This
- was discussed in the documentation for PGP, where he discusses this idea
- in full.
