RawSecureSocket class

RawSecureSocket provides a secure (SSL or TLS) network connection. Client connections to a server are provided by calling RawSecureSocket.connect. A secure server, created with RawSecureServerSocket, also returns RawSecureSocket objects representing the server end of a secure connection. The certificate provided by the server is checked using the trusted certificates set in the SecurityContext object. The default SecurityContext object contains a built-in set of trusted root certificates for well-known certificate authorities.

Constructors

RawSecureSocket()

Properties

peerCertificate → X509Certificate: Get the peer certificate for a connected RawSecureSocket. If this RawSecureSocket is the server end of a secure socket connection, peerCertificate will return the client certificate, or null, if no client certificate was received. If it is the client end, peerCertificate will return the server's certificate.
