    Hallo,

    how to use QSslCertificate to check against CRL (Revokation List)? I have not found any Function to add CRL files or any QSslCRL class.

    Anyone?

      Hi,

      Just an educated guess but I would say because it's outside of Qt's scope.

      You can see here an interesting thread about how to do that with OpenSSL.

        @SGaist
        why is it outside Qt's Scope? Why would it be difficult to implement it?

        As far as I know I have suggested to change to Botan instead of OpenSSL as underlying TLS/SSL Library.

          @SeppyQT said in Qt: Check SSL Certificate if it was revoked (CRL) file:

          From the looks of it, most of the developers do not need to do that low level check themselves and will rely on the platform to have up to date certificate data.

          You are welcome to submit a patch adding that feature for the supported platforms.

          Where is that suggestion ?
