[gnutls-help] Improving X.509 certificate validation errors

[Nikos Mavrogiannopoulos]

Hi Martin,
 Would you like to move your questions to our gitlab.com site as an
issue to initiate the discussion? I am not sure all in the development
team follow this mailing list.

regards,
Nikos

Our goal is to simplify the ecosystem by consolidating the errors and their documentation in one place, providing replicable example certificates for all validation errors and by explaining better what the individual errors mean. The project is live at https://x509errors.org/
