I've installed a ssl certificate from https://www.startssl.com/ in a server running with plesk. The website is the following: https://refood.sal-pimenta.pt/
As you can see the certificate is fine but not that good in terms of security (sha1 and 2048 Bits key), and this fact is pointed out if you use Chrome. This is really odd because the certificate I have in my PC, the one I uploaded to the server, as sha256RSA for signature with a key of 4096 Bits.
I checked the public keys and they are obviously different, as well as the certificate CA.
Is this normal? Thanks for your time and I'm sorry if this not that related to cryptography but it seemed the right place to ask.
