I’ve been trying to get my head around cryptography on the iPhone so that I can create a native iPhone app (iPasskeep) that interoperates with my JPasskeep password keeper application. It has taken a while to get my head around CommonCrypto APIs - how to use them, how not to use them and their limitations. It then took a bit of fiddling to find the right incantations in Java to get an interoperable cryptographic transformation....
I've released a new version of my long-running password keeper application: JPasskeep. This new release is now able to handle a Command-Q keystroke on the Mac, giving a user (i.e. me) an chance to save any updated entries. No more mousing around to close a window. The actual mechanism to do this was to reflectively call Apple's EAWT application classes to allow me to register the correct event listener. Hmm, run anywhere with java GUI apps....
I need to stop distributing JPasskeep source code as zip files - yuck. So for anyone who may be interested at what lurks under the cover of the pretty GUI the code is now available on GitHub - http://github.com/tomcz/jpasskeep/tree/master. Comments, suggestions, bugs, patches, forks, or pitch-forks are always welcome; even if sometimes ignored ;-)...
