WebAES-256 is a kind of block cipher. It takes as input a 32-byte key and a 16-byte string, called the block and outputs a block. We use AES in a mode of operation in order to encrypt. The solutions above suggest using CBC, which is one example. Another is called CTR, and it's somewhat easier to use: WebStep 2: Key exchange The sending and receiving computers exchange public keys with each other via a reliable channel, like TCP/IP. The private keys are never exchanged. Step 3: Encryption The sending computer encrypts the secret data using the receiving computer's public key and a mathematical operation.
