A Very Basic Introduction to AES-256 Cipher

AES stands for “Advanced Encryption Standard” and is a specification that has selected the Rijndael cipher as its symmetric key ciphering algorithm. Using AES, a message can be encrypted with a key (like a password) and no one except the key holder can decrypt the message. This is useful for many reasons, but a good example is a password manager that encrypts all of the user’s passwords using one master password. This is how Qvault, our free open-source password manager operates.
