Encryption is the process of converting you data in to other obscure form so that no one can read it. Encryption can also be done using batch files. Batch files are scripting programs in windows which can be used to program small automatic operations. To do this open a notepad to write the batch program. First turn of the echo by inserting the command '@echo off'. Now write the rest of the program as shown in the video. Now save the image as a bat file. Now you can encrypt this batch file. To do this set different variables with values such that the concatenation of all the variables gives you the original commands. In this way encrypt the whole commands in the batch program. This video shows how to encrypt a batch file in windows.
