I'm trying to understand the TLS 1.2 restrictions and signature algorithms
and how they interact.  Is there a relation between the signature algorithm
that is negotiated between client and server and the algorithm which signed
the server certificate?

Does that affect the hash algorithm of TLS 1.2 - or is that always SHA256?

 

For example, if I've got a server configured with a server certificate
signed with SHA256, can it still establish a connection using the
TLS_RSA_WITH_AES_256_CBC_SHA?

 

Does the signature algorithm for a certificate affect which Ciphersuites can
be negotiated and used?
