In contrast to symmetric ciphers, there are asymmetric ciphers (also called public-key cryptography). These ciphers use two keys: a public key and a private key. The keys are mathematically related but still distinct.

WebMar 4, 2015 · PKI. PKI (public key infrastructure) is a hybrid of symmetric and asymmetric encryption. The handshake uses asymmetric encryption to exchange the secret key used for symmetric encryption. Once the secret key is exchanged, the rest of the communication uses symmetric encryption. Better performance can be enjoyed with increased security. WebApr 11, 2024 · What Is a Private Key? A private key is a cryptographic key used in an encryption algorithm to both encrypt and decrypt data. These keys are used in both public and private encryption: In private key encryption, also known as symmetric encryption, the data is first encrypted using the private key and then decrypted using the same key.
