Notepad++ is there such an encryption plugin?

Question

Notepad++

I know there is a plug-in for notepad - securePad but it works on a button, you have to press enter a password, etc.
Is there such a plug-in so that the file opens in notepad and is visible as text.
And if you open it with notepad or text, it would be encrypted.
Well, naturally, when opening, enter the decryption password and when saving it, it was encrypted and saved, and did I see a readable text on the screen?
Well, or something like that.
Truescript not to offer) it's not that.
It is necessary to me that the plug-in was type as the driver. so that the decrypted text is only in memory and displayed on the screen, but it is saved and always lies on the disk in encrypted form.
