A problem with asymmetric encryption, however, is that it is slower than symmetric encryption. It requires far more processing power to both encrypt and decrypt the content of the message. To use asymmetric encryption, there must be a way for people to discover other public keys.
Two of the most widely used encryption methods are Public key (asymmetric) encryption and Private key (symmetric) encryption. The two are similar in the sense that they both allow a user to encrypt data to hide it from others, and then decrypt it in order to access the original plaintext.
