Is there any way to make npp ask for a password everytime I open it and if entered it would open last session? Further more is it possible to make it encrypt all the currently opened files/tabs when npp is closed? And automatically decrypt when opened and password entered correctly?
I tried the Securepad plugin that encrypts files but it is hard to use since I need to enter password each time to encrypt/decrypt and for each tab/file.
There iare NppCrypt and NppDarkCrypt plugins, but they operate at the file level, so you'd get the same problems, except perhaps for the auto encrypt/decrypt part - I don't use them.
As for protecting the use of N++ with a password, this looks more like a Windows integration problem. I'd scour the Net for a small freebie that does the job, if it exists.
