A cipher suite specifies one algorithm for each of the following tasks: * Key exchange * Bulk encryption * Message authentication So you may see something like: PSK-AES-SHA256 Key exchange algorithms Key exchange algorithms protect information required to create shared keys. These algorithms are asymmetric (public key algorithms) and perform well for relatively
It happens in all HTTPS connections. Certificate phase, chose cipher suite 1. Client send hello, with supported cipher/version all other information 2. Server send hello, with certificate, and done hello 3. Premaster key done Symetric key exchange using asymetric public key in certificate 1. Computer installed many CA 2.
