WebMay 25, 2024 · TLS 1.3 allows two parties to establish a shared session key from an out-of-band agreed pre-shared key (PSK). The PSK is used to mutually authenticate the parties, under the assumption that it is not shared with others. This allows the parties to skip the certificate verification steps, saving bandwidth, communication rounds, and latency. In … WebTLS uses both symmetric encryption and public key encryption for securely sending private data, and adds additional security features, such as authentication and message …
