Hi community,

I want to ask if there’s a way to add custom attributes in x509 certificates while using Vault PKI engine for ex.

  1. adding custom attributes in subject of issued certificate
  2. customizing serial number

This is needed for compliant purposes to specific protocols (for ex. D. cinema SMPTE ST 430-2)

Looking urgently for the help.

thanks
