New content

A few new pages have been added to the site that you may be interested in:

• The section on Java cryptography now considers password-based encryption, which we not too surprisingly conclude is fraught with difficulties! At present, we look at the PBE algorithms provided as standard in Sun's Java 6 implementation, although we unfortunately conclude that none of them are terribly great!
• The section on Swing User interfaces covers various common topics, including a "rogue's gallery" of common Swing components, with a list of common constructors and listeners for those components, plus some hints on adding listeners to your code.

Further pages are planned for both of these sections very shortly. Watch this space!
