Nice little app!
A very similar app is Steganos LockNote http://www.steganos.com/?content=locknote&language=en
, which has a few additional features, like searching in the file and creating an encrypted exe from an existing text-file by dragging it into the program window, which creates an exe-file in the same folder with the same name as the txt-file. Also it's icon has got more colours
On the negative side, it takes almost 300 kb, which is more than 7 times the size of fSekrit! I bet the huge image in the about dialog uses about the same space as this whole program does.
• Ability to convert txt-files by dragging and dropping into program
• Unicode (UTF-8) support would be nice, but let the user have the option to download a version without unicode with smaller filesize.
Keep up the good work!
