Google announced that they are fading out support for SHA1 based signatures of SSL certificates:

For some ****** reason I am not allowed to post links until I've posted more than 5 messages. Instead of posting 5 senseless messages I decided to obfuscate the needed link here, sorry for any inconvenience. <_at_>Kerio: I recommend switching off that thing. Persons who want to spam can do it anyway ...

Therefore I'd like to create new keys within Kerio Connect (8.3.2) which are equivalent to:

openssl req -new -newkey rsa:2048 -nodes -sha256 -out www.example.com.sha256.csr -keyout www.example.com.key 

(to get signatures for SHA2/256 bit)

How can I do that?

You can do it exactly as you posted - using openssl command. Then you can have your .csr signed by CA and import cert and .key into Kerio Connect.
