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.

However, decryption keys (private keys) are secret. This way only the intended receiver can decrypt the message.
