HTTP TLS Mutual Authentication (Client-Side Certificate)

See more HTTP Examples

This example demonstrates what to do when a TLS connection requires a client-side certificate, also known as "two-way authentication" or "mutual authentication". The Chilkat API provides a few standard methods for setting the client-side certificate:

• SetSslClientCert
• SetSslClientPem
• SetSslClientPfx

These methods are present in any Chilkat class that has SSL/TLS functionality. When the SSL client cert is set via one of these methods, it tells the API to use it for two-way (i.e. mutual) authentication. In all possible tasks, whether it is a POST, GET, PUT, an Amazon S3 method, etc., the only thing required for implementing the two-way authentication is to make a successful call to one of the above SetSsl* methods.

C++

#include <CkHttp.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkHttp http;

    //  Set the certificate to be used for mutual TLS authentication
    //  (i.e. sets the client-side certificate for two-way TLS authentication)
    success = http.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword");
    if (success != true) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    //  Note: The certificate used for the client-side of TLS mutual authentication
    //  must have the associated private key available. (PFX files typically store both
    //  the certificate and associated private key.)

    //  At this point, the HTTP object is setup with the client-side cert, and any SSL/TLS
    //  connection will automatically use it if the server demands a client-side cert.
