How to use:
1. Browse for the source .dat file.
2. Browse for the destination folder you would like to save the decrypted file or encrypt the file from.
3. Decrypt the file
4. Browse to your destination folder and make your changes on Selectedfile(Decrypted).txt.
5. Once changes are made, (Source and Destination DOES NOT NEED TO BE CHANGED) All you do is just click Encrypt
