GPGME (GnuPG Made Easy). It's a high level encryption library in C and is LGPL licensed.
You could possibly consider an OpenPGP-based solution. This would provide you with the functionality you desire and would scale to support arbitrary data sizes, unlike a solution based purely on asymmetric encryption (with no transport key).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
