X509 Basic Constraints and PolicyInformation

[alexrocks59]

We currently are using this library to generate self-signed certificate for TLS communication with a 2030.5 meter agent. The library is great and we were able to at least pass the TLS handshake passing the generated self-signed certificate.

The 2030.5 server is now passing us a bad certificate alert and not quite sure what is causing it. We have a sample cert/key generated via openssl which passes this communication. When comparing the cert generated by the library, we found this lacked the extensions basicContraints and PolicyInformation. I started looking at the library code and was wondering if you can give us some guidelines and info we can use to possibly implement these? Thanks so much

Hi, you can implement support for those extensions and then create a pull request similar to the one i did for the key usage here https://github.com/Ephenodrom/Dart-Basic-Utils/pull/81/files

You just have to read the certificate protocol/documentation on how your extensions have to be encoded.
