![]() To continue following this tutorial we will need the following Python library: cryptography. We will follow symmetric encryption which means using the same key to encrypt and decrypt the files. Let’s see how we can encrypt and decrypt some of our files using Python. The process of encryption/decryption is called cryptography. The only way to access the file information then is to decrypt it. So what is encryption? It is a process of converting information into some form of a code to hide its true content. This is where file encryption plays a big role and provides security and convenience sought by parties engaged in file transfers. Some information can be password protected (emails, logins) while other information being transferred via emails or FTP lacks efficiency if protected by some keyword. In the evolving world of data and information transfer, security of the file contents remain to be one of the greatest concerns for companies. Complete object-oriented programming example. ![]()
