I have a Windows 2003 server running Exchange 2003 and I am trying to renew the current certificate but when I try to renew it through RapidSSL, I get the following error;
Your CSR contains a key size that is no longer considered secure. Security best practices require a minimum key size of 2048 bits. Please submit a new CSR with a minimum 2048 bit key size.
How do I fix this?
