Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

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. Xbase++

LOCAL nSuccess
LOCAL oSock
LOCAL nBTls
LOCAL nPort
LOCAL nMaxWaitMs

nSuccess := 0

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

oSock := CreateObject("Chilkat.Socket")

//  Set the certificate to be used for mutual TLS authentication
//  (i.e. sets the client-side certificate for two-way TLS authentication)
nSuccess := oSock:SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx", "pfxPassword")
IF (nSuccess != 1)
    ? oSock:LastErrorText
    oSock:destroy()
    RETURN
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).
nBTls := 1
nPort := 443
nMaxWaitMs := 5000
nSuccess := oSock:Connect("www.example.com", nPort, nBTls, nMaxWaitMs)
IF (nSuccess != 1)
    ? "Connect Failure Error Code: " + Str(oSock:ConnectFailReason)
    ? oSock:LastErrorText
    oSock:destroy()
    RETURN
ENDIF

//  At this point, the Socket object is connected and authenticated using the client-side cert

//  ...
