Description

RFC5280 describes this extension as follows:
When a conforming CA includes a cRLDistributionPoints extension in a certificate, it MUST include at least one DistributionPoint that points to a CRL that covers the certificate for all reasons.
I provided a test case that included a CRL distribution point extension, but the extension value was empty, which does not comply with RFC5280.
I used the this certificate to conduct a format conversion experiment.Golang throws error for certificate: invalid CRL distribution points, but openssl incorrectly conversion successful.
