I really need to get up to speed on cryptography. I've been a software developer for a while but haven't had a chance to get into it. Part of the reason is time, the other reason is that I haven't a clue where to start. I've heard about the books Security Engineering and Cryptography Engineering. Are they good books for someone new to all this?
