FileEncrypter

This program is used for encrypting and decrypting files using AES 256-bit key encryption.

A user-defined password can also be defined for secure encryption and decryption. All given passwords are converted to a 256-bit key using SHA256 Hash Algorithm. Since hash for any two given passwords can never be the same, 256-bit key generated is also unique, thus the confidentiality of the encrypted file is guaranteed.

Installation
