I was going through the GNU TLS 2.9.9 source code that support TLS 1.2.
I have following doubts in gnutls that support of TLS 1.2 rfc
1. While selecting server cert and chain, GNUTLS just compare server
certificate with client requested sign/hash extension, not the whole chain.
if it matched one of the server certificate , it will select the chain.
but according to TLS 1.2 , whole chain must matched with one of the
sign/hash algo supported by client.
Is my understanding is correct ..?
If not , how and which part of code GNU TLS compare the sign/hash algo
with the whole chain.
2. While selecting client cert list in response of client cert request, GNU
TLS doesn't use parsed sign/hash algo supported server.
it just use the cert type and dns name for selecting cert chain ,not
but according to TLS 1.2 , client must compare and select cert chain
that matches with one of the sign/hash supported by server.
Please let me know if am correct or not.
Please provide some of your valuable inputs which clarify above point
