Types

type Server

type Server struct {
	// contains filtered or unexported fields
}

Server is an HTTP server that returns JA3 information. This server only supports HTTP/1.1 and HTTP/2.

This server will use its own internal CA. You should use Server.ClientConfig to obtain a suitable tls.Config or Server.CertPool to obtain a suitable x509.CertPool. If you use Server.CertPool keep in mind that you also need to specify a ServerName in the tls.Config for an handshake to complete successfully. By default [Server.Config] uses "example.com" as the server name but you can override that.

Please, use the NewServer factory to create a new instance: the zero-value Server is invalid and will panic if used.

func NewServer

func NewServer(alpn ...string) *Server

NewServer creates a new Server instance.

func (*Server) CertPool

func (p *Server) CertPool() *x509.CertPool

CertPool returns the internal CA as a cert pool.

func (*Server) ClientConfig

func (p *Server) ClientConfig() *tls.Config

ClientConfig returns a tls.Config where the ServerName is set to "example.com" and the RootCAs is set to the value returned by the Server.CertPool method.

func (*Server) Close

func (p *Server) Close() (err error)

Close terminates a running Server instance.

func (*Server) Endpoint

func (p *Server) Endpoint() string

Endpoint returns the server's TCP endpoint.

func (*Server) URL

func (p *Server) URL() string

URL returns the server's URL, which is guaranteed to contain an explicit port even in the very unlikely case in which the randomly selected port is 443/tcp.
