Is there any way to modify a ssl certificate? I don't want to change any of sections relating to authentication, only some of the surrounding data, e.g. Issuer or X509v3 Key Usage. Is there any tool that will take an existing certificate and the new value for a field, and output an identical certificate with the modification made? Or is the only solution to generate a new certificate from scratch and include the modifications there?


You'll need a new certificate.
