RE: SSL ciphers -- MIDRANGE-L

Paul,

More details on the SSL/TLS handshake process can be found here:
http://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_handshake

A more thorough discussion of the relationship between the certificate and the public key used in the initial exchange of session parameters is available here:

Pete,

Now you have me wondering.
So are all the pieces related, Cert, SSL ver, cipher, etc.
I wish I could find a better link that explains the cipher selection, or someone explain how this whole process works.
This was the best link I found thus far.

"The certificate and the cipher have nothing to do with one another. "

Hmmm. News to me then. My understanding was that we needed to request a new Certificate from Comodo. Current certificate shows that it supports Signature algorithm SHA1RSA with a Signature hash algorithm of SHA1. Which is why Chrome flags our website with the red slash on our SSL connection. My understanding was that that the SHA1 cert would only negotiate a SHA1 cipher request (so the cipher and cert WERE related) so I guess I need to do more reading.....

Could/would the iSeries WC cert affect the cipher negotiation?
I still have a SHA 1 WC cert, the new SHA 256 WC cert not yet enabled.
