(VB.NET) HTTP TLS Mutual Authentication (Client-Side Certificate)
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:
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.
' This example assumes the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim http As New Chilkat.Http ' Set the certificate to be used for mutual TLS authentication ' (i.e. sets the client-side certificate for two-way TLS authentication) Dim success As Boolean = http.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword") If (success <> True) Then Debug.WriteLine(http.LastErrorText) Exit Sub End If ' 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
