WinCrypto

WinCrypto is a basic and simple tool to password-protect your files so no one can access them without your permission.

The program interface doesn't unduly complicate the file protection process. It just shows you the filepath to search for the original file and the one where the output will be saved.

Below the bars displaying these two locations is the section where you set your password. That done, just click 'encrypt' to protect your data.

WinCrypto uses the RC4 encryption algorithm and is able to hide all types of files, regardless of size or format.

To decrypt the files, it's the same process. First search the directory where you saved your protected files. Then hit 'decrypt,' enter the password, and from there you'll see the original version.

Another great thing is that you can use this program without any installation.
