nClient hello (clientèserver)
n“Hi! I speak these n ciphersuites, and here’s a 28-byte random number (nonce) I just picked”
nServer hello (clientçserver)
n“Hello. We’re going to use this particular ciphersuite, and here’s a 28-byte nonce I just picked.”
nOther info can be passed along (we’ll see why a little later...)
