// AUTHENTICATION MODES
//
// There are several levels of authentication that TLS/SSL supports.
// Read more about this in "man SSL_set_verify".
//
// 1. The server sends a certificate to the client but does not request a
// cert from the client. This is common for most HTTPS servers. The browser
// can verify the identity of the server, but the server does not know who
// the client is. Authenticating the client is usually done over HTTP using
// login boxes and cookies and stuff.
//
// 2. The server sends a cert to the client and requests that the client
// also send it a cert. The client knows who the server is and the server is
// requesting the client also identify themselves. There are several
// outcomes:
//
// A) verifyError returns null meaning the client's certificate is signed
// by one of the server's CAs. The server now knows the client's identity
// and the client is authorized.
//
// B) For some reason the client's certificate is not acceptable -
// verifyError returns a string indicating the problem. The server can
// either (i) reject the client or (ii) allow the client to connect as an
// unauthorized connection.
//
// The mode is controlled by two boolean variables.
//
// requestCert
// If true the server requests a certificate from client connections. For
// the common HTTPS case, users will want this to be false, which is what
// it defaults to.
//
// rejectUnauthorized
// If true clients whose certificates are invalid for any reason will not
// be allowed to make connections. If false, they will simply be marked as
// unauthorized but secure communication will continue. By default this is
// true.
//
//
//
// Options:
// - requestCert. Send verify request. Default to false.
// - rejectUnauthorized. Boolean, default to true.
// - key. string.
// - cert: string.
// - clientCertEngine: string.
// - ca: string or array of strings.
// - sessionTimeout: integer.
