When parsing an X.509 certificate, it's convoluted to extract certain parts of the certificate contents.

Describe the solution you'd like
When parsing a certificate, I would like the output in a structured data format like JSON.

Describe alternatives you've considered
Extracting the required information via regular expressions.

Additional context
After parsing into a structured format, it's more convenient to get the required data by JPath/XPath expression.
