Encryption is the process of translating plain text data (plaintext) into something that appears to be random and meaningless (cipher text). Decryption is the process of converting cipher text back to plaintext.
For smaller and simpler files (like Text files) we can use DES algorithm, but for other type of files such as a video, we’ll have to use AES or some other algorithm. For this example we’ll be using AES algorithm. AES is a new cryptographic algorithm that can be used to protect electronic data. Typically, AES is an iterative, symmetric-key block cipher that […]
