Invalid Digital Signature of generated certificates

jeffreyman

Hi,

I use alfresco-ssl-generator to generate certificates for repository, solr and client. However, the generated certificates show "This certificate has an invalid digital signature" error. I have no idea how to fix it. Please help.

Hi Sufo,

After install the new CA cert in local user, the certificates look good. I think it is a viewing problem, not certificate itself.

Thanks a lot.

Attaching the certificate should help to find out the problem.

Hi,

I don't know how to attach file. Here is text format.

This is the public part of the certificate.

It seems to be ok.

Not sure if the private part has some problem...

Hi,

Why it show error when viewing the certificate in windows?

A few months ago, I generate the certificates (same method) that do not have such error.
