(PureBasic) Socket TLS Mutual Authentication (Client-Side Certificate)This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate.
IncludeFile "CkSocket.pb" Procedure ChilkatExample() ; This example assumes the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. sock.i = CkSocket::ckCreate() If sock.i = 0 Debug "Failed to create object." ProcedureReturn EndIf ; Set the certificate to be used for mutual TLS authentication ; (i.e. sets the client-side certificate for two-way TLS authentication) success.i = CkSocket::ckSetSslClientCertPfx(sock,"/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword") If success <> 1 Debug CkSocket::ckLastErrorText(sock) CkSocket::ckDispose(sock) ProcedureReturn EndIf ; Note: The certificate used for the client-side of TLS mutual authentication ; must have the associated private key available. (.pfx/.p12 files typically store both ; the certificate and associated private key.) ; Establish the connection using the socket object (with client certificate authentication). bTls.i = 1 port.i = 443 maxWaitMs.i = 5000 success = CkSocket::ckConnect(sock,"www.example.com",port,bTls,maxWaitMs) If success <> 1 Debug "Connect Failure Error Code: " + Str(CkSocket::ckConnectFailReason(sock)) Debug CkSocket::ckLastErrorText(sock) CkSocket::ckDispose(sock) ProcedureReturn EndIf ; At this point, the Socket object is connected and authenticated using the client-side cert ; ... ; ..
