Cryptography engineering

Cryptography has historically been viewed as one of the hardest-to-get-right, yet most robust defenses against data leakage, tampering, and misuse.

Rolling your own crypto is a sin unless you're a cryptographer. Even then, it's still a bit of a sin. We know limits to our knowledge, and we understand where to roll, where to pick existing stuff, and how to adapt it to your product.
