Store your most valuable notes in a LockNote. Hide your everyday notes in a safe place. Application and document in one: the mechanism to encrypt and decrypt a note is part of it. Secure, simple, independent. No installation required.
A very simple open source utility which provides AES 256bit encryption for your text notes. Just drag and drop the text file on the exe and get a encrypted (exe) copy of the input file.
