So, you equate "best, and most secure" with "blowfish, RSA, PGP"? Yeah. That's why the NSA spends billions on new crypto because the commercial market is the best?
The only truely secure encryption is a one-time cipher, based on radioactive decay, which generates true random numbers. Blowfish, RSA, and PGP are "highly secure," based on the key length. If you don't have an unlimited government budget, like the NSA, you will have to make due with encryption like these. How do you feel about DES, and the way the government strong-armed IBM to shorten the key length when it was developed?
I hate to break it to you, but if you go up against a government, you're going to lose. Try not to forget, that not only do they have unlimited budgets, but they can also use deadly force.

true. They are secure, but not "the best", not by a long shot. Besides, the military systems I have used never used only cryptology to ensure security. They also had additional security through the transmission means, contents, etc. I was a DoD space systems specialist for many years, and used some of the most secured systems out there for satellite command & control. PGP, IDEA? I would expect the NSA already has those algorythms in silicon and can crack them at near real-time speed. I do not know that for fact, but that would be the NSA's MO. I have friends who are FBI and they say that the NSA does NOT cooperate with them. Unless the matter is a national security issue, they have to beg and pull strings to get anything so much as looked at. It seems the military feds have a distain for the commercial feds.
