Encrypting data: Use AES in CTR (Counter) mode, and append an HMAC . AES is about as standard as you can get, and has done a good job of resisting cryptologic attacks over the past decade. Using CTR mode avoids the weakness of ECB mode, the complex (and bug-prone) process of padding and unpadding of partial blocks (or…
I am speaking today at BSDCan'09 about my work on the scrypt key derivation function. In the context of hardware brute-force attacks, scrypt is thousands of times more secure than existing "best practice" solutions such as bcrypt and PBKDF2; in fact, under reasonable assumptions it is provably as strong as possible…
First things first: Why use a composition of encryption and MAC instead of a single primitive which achieves both? Because people are very good at writing bad code. In my experience on the FreeBSD security team, writing dozens of security advisories, there are three types of code which are especially prone to have…
