This page offers a better way to create a strong, yet easy to remember, passphrase for use with encryption and security programs. Weak passwords and passphrases are one of the most common flaws in computer security. Take a few minutes and learn how to do it right. The information presented here can be used by anyone…
An excellent (if a bit dated) article/tutorial on exploiting buffer overflow vulnerabilities. It was written by Aleph One for Phrack 49.
