EasyCrypt

EasyCrypt is a tiny utility that gives you the possibility of encrypting a file by creating a key file as a form of dependency. It can be seamlessly handled, even by users with little experience in software apps.
After a brief installation procedure, you are greeted by a small, regular window with a plain layout. EasyCrypt doesn't strive in the visual department, but we must take into account that the app has not been updated for a very long time.
Before initializing the encryption procedure, you are required you specify the temporary directory.
So, you can point out the file that you want to encrypt, establish the output directory and file name, as well as generate a key file, based on the security level that you decide. Decrypting a file is done in a similar manner.
In addition, you can securely erase an item from the computer, set to EasyCrypt run in the system tray area at startup, as well as to automatically run at Windows boot. Plus, you can adjust the opacity of the primary application window.
EasyCrypt finishes an encryption job rapidly while using a low-to-moderate quantity of CPU and system memory, thus it doesn't hog the computer resources. No error dialogs have been shown in our tests and the app did not hang or crash.
On the other hand, EasyCrypt implies going through the trouble of creating a secondary file that you must keep somewhere safe, in order to decrypt the original item, while other tools are more powerful in the file security area.
