Sigh. Yep, I also ran into trouble on my first jump in a few pages from the start:

Ummm.... when using RSA to encrypt something (e.g., a DEK) you use the other party's public key, and of course the other party uses its private key to decrypt.

How do you get stuff like this so wrong??? Sheesh, even flipping a coin gives you a 50-50 chance.
