lock noteSo you are a Nuclear scientist and hold top secret information about the Nuclear Warfare of your country? (I know many nuclear scientists love to read my articles!) Want to transfer this information to someone but fear that it may be trespassed. Why don’t you try encryption? Because its complicated? Are you sure? Because what I am going to mention might just change you view about it.

Okay first off I admit the all the nuclear bla bla could be termed as exaggerating . However there are lots of things you might need only authorized person to be able to have a look on like your passwords, some important notes and so on you think, I know there is plenty of stuff. The application I am talking about is LockNote. LockNote is a document and encryption mechanism in one single application.

First off download it here for free.

Run Locknote.exe, type in your confidential text and choose Save as. Then you will be needed to enter a password and that’s it. Now to open the file you will need the password you just provided. Once you open the file, you can make changes and then save all the changes in the file. It decrypts the file when you open the file and encrypts it when you save the file all on the fly.

Moreover you can also drag and drop any text file on the executable to quickly encrypt it. In case you are wondering how secure it is, let me mention that it uses AES 256 bit encryption, which if you don’t know what it is, I assure you it is secure for your confidential notes 🙂 LockNote is portable and doesn’t need any installation, so you can use it from your USB drive as well
