Cannot find RemoteCertificateValidationCallback in ClientWebSocketOptions

Hello i am trying to bypass ssl certs by setting RemoteCertificateValidationCallback in the websocket options but they dont exist?

        Socket = new ClientWebSocket();
        Socket.Options.RemoteCertificateValidationCallback = delegate { return true; };

        Socket = new ClientWebSocket();
        Socket.Options.RemoteCertificateValidationCallback = delegate { return true; };

error:

'ClientWebSocketOptions' does not contain a definition for 'RemoteCertificateValidationCallback' and no accessible extension method 'RemoteCertificateValidationCallback' accepting a first argument of type 'ClientWebSocketOptions' could be found (are you missing a using directive or an assembly reference?)

yes, it says it is only available in .NET Core you are probably using .NET Framework

ah duh, sorry. do you think there is any way to bypass certs on clientwebsocket then without that?

reflectronic•8mo ago

yes hold try setting ServicePointManager.ServerCertificateValidationCallback

mynarcoOP•8mo ago

yup i have already set that

        ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

        ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

still not workign thourhg

reflectronic•8mo ago

presumably you are getting an exception because the validation fails what is the exception, and what is the call stack

mynarcoOP•8mo ago

yes, i have noticed the two problems i am getting are the fact that - when i set the scheme to wsit returns Unable to connect to remote server - when i use wss it returns the ssl verification error 1sec

which is up

reflectronic•8mo ago

ah. i guess you are using xamarin. hm

mynarcoOP•8mo ago

hm? what is xamarin?

reflectronic•8mo ago

hm. well. maybe not

mynarcoOP•8mo ago

this server is written in python using sockets(because im lazy :p)

reflectronic•8mo ago

is it unity? what are you using to write this

mynarcoOP•8mo ago

godot but i am using c#'s web library to handle web stuff

reflectronic•8mo ago

well, uh, i would suggest updating to a newer version of godot, which would let you use RemoteCertificateValidationCallback

mynarcoOP•8mo ago

unfortunately that isnt possible :(

mynarcoOP•8mo ago

the games codebase is already established and migrating from godot 3.5 to godot 4 is equivalent to rewriting the entire game. here is the codebase https://github.com/anthony-63/FluxV2

can you try

ServicePointManager.CertificatePolicy = new NullCertificatePolicy();

class NullCertificatePolicy : ICertificatePolicy
{
    public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem)
        => true;
}

ServicePointManager.CertificatePolicy = new NullCertificatePolicy();

class NullCertificatePolicy : ICertificatePolicy
{
    public bool CheckValidationResult(ServicePoint srvPoint, X509Certificate certificate, WebRequest request, int certificateProblem)
        => true;
}

this seems to be a known issue https://github.com/mono/mono/issues/8660
