For information, I have been working since the last version only in one new feature.

That is to add a password protection on opening the smscon-editor. It requires a couple of new dialog windows (one for entering the password and a second to change the password.), buttons here and there, some serious change on the code to not execute things before authorized etc, and of course new code to handle and make those actions (read, save, compare passwords etc).

I'm quite there but I'm missing one important library to make it perfect.

Does anyone has a pointer on a simple and nice crypto library to propose?
