This is a small project that talks about encrypting and decrypting a file. The algorithm is a type of symmetric key stream cipher algorithm. The algorithm takes password and source file as an input. The password used at the time of encryption can only be used at the time of decryption, otherwise there is no way to decrypt a file.
This small script/app can be used for encrypting any type of file with a password protected feature. Java was used as a base so, it can be run on any OS.
