The purpose of this app is to encrypt your file into total gibberish, which is useful if you want something like a master file to store all your online passwords or send secret messages over email. The encryption is based on AES 128 bit standard. So far it can support .txt files and ..... pretty much everything else. :-D
Java version is finished. Download the chain_encryption.jar from my github releases. Make sure java runtime enviorment from the oracle website is installed beforehand. I am not packaging the jar into a windows .exe executable because it defeats the whole purpose of cross platform language like java. You will need to know how to run a jar on your own.
Latest jar is thoughly tested on both windows and linux. Mac OS is not yet tested.
