Hi,

I am want to send client certificate, client key exchange and client verify in 
a single handshake message which appears as multiple handshake messages in a 
single record. But to sent the client verify I need to first make a hash of 
previous messages(client certificate and client key exchange) to create the 
signature.

Can anyone help me to find the function in OpenSSL 1.1.1-dev  xx XXX xxxx that 
can do a proper transcript(digest or hash not clear). I tried using 
ssl3_finish_mac() on the message containing client certificate and client key 
exchange and then tried to generate the signature in certificate verify message.
But it is giving me a digest error. I am new to the mailing list want a bit of 
help to proceed forward stuck here. Please reply in case if anything is not 
clear.

Regards,
Saiteja
