Support for certificates about justjwt

[deftomat]

Hi @renefloor,
to be honest, I don't know if there is any Dart library which can extract public key from certificate.
However, you can use openssl with Process.start to extract it. There is an example, which describes how you can pipe data to any process and read result.

Also, there is a library, which can verify Google JWT and it is also using a public key in a slightly different format.

So, your job is just to create a stream transformer, which will receive a certificate from google servers, pipe data to openssl and then await for a public key in a requested format.

Thanks @deftomat for your response.
I'll look into that. The Google JWT seems more logical than the Firebase JWT..
