WebWhen transmitting electronic data, the most common use of cryptography is to encrypt and decrypt email and other plain-text messages. The simplest method uses the symmetric or "secret key" system. Here, data is encrypted using a secret key, and then both the encoded message and secret key are sent to the recipient for decryption. The problem? WebAsymmetric encryption is also known as public key encryption. In symmetric encryption, there is only one key, and all communicating parties use the same (secret) key for both encryption and decryption.
