>>44828189I saw this thread and I couldn't keep quiet. I am right now doing a masters in security informatics at JHUISI, which is the premier security masters on the planet. That obviously doesn't mean I'm a crypto expert by any means, but I hope it gets you to think for a brief second about what I'm saying.
If you actually want to encrypt anything, just use gpg. I know that it isn't very user friendly, but the fact is that it's been around so long and is so well-verified that any other option pales in comparison.
Cryptography is extraordinarily complicated, and even a small mistake can tank the entire scheme. Furthermore, the money and expertise to verify its use are in extremely short supply. As a result, the other options are fairly likely to be flawed.
Choose gpg.
