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.

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

$oHttp = ObjCreate("Chilkat.Http")

; Set the certificate to be used for mutual TLS authentication
; (i.e. sets the client-side certificate for two-way TLS authentication)
$bSuccess = $oHttp.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword")
If ($bSuccess <> True) Then
    ConsoleWrite($oHttp.LastErrorText & @CRLF)
    Exit
EndIf

; 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
