Pavel, folks here are being hard on you guys because historically, 9 out of 10 times "independent thinkers" who roll out their own crypto stacks get something wrong. That's why if you want to market your app to this crowd, you'll have a hard time selling something that is not what is a currently recommended crypto stack. Emphasizing that it is the NSA who recommends it is just a pasive-aggressive conspiracy theorizing. It may very well be the case that the NSA have ways of cracking their "Suite B", but we have no evidence of that, and if they do, do you really think that your ad-hoc solution would do much better against them?
