(VB.NET) Use HTTPS Client Certificate from .cer and .key FilesDemonstrates how to load a cert + private key from .cer and .key (base64) files and use it for mutual TLS authentication (client-side certificate).
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim http As New Chilkat.Http Dim cert As New Chilkat.Cert Dim privKey As New Chilkat.PrivateKey ' Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile. Dim success As Boolean = cert.LoadFromFile("qa_data/certs/sample_cert_a.cer") If (success <> True) Then Debug.WriteLine(cert.LastErrorText) Exit Sub End If ' Load the private key. Dim bd As New Chilkat.BinData success = bd.LoadFile("qa_data/certs/sample_key_a.key") success = privKey.LoadAnyFormat(bd,"privateKeyPasswordIfNecessary") If (success <> True) Then Debug.WriteLine(privKey.LastErrorText) Exit Sub End If ' Associate the private key with the cert. success = cert.SetPrivateKey(privKey) If (success <> True) Then Debug.WriteLine(cert.LastErrorText) Exit Sub End If ' Set the certificate to be used for mutual TLS authentication ' (i.e. sets the client-side certificate for two-way TLS authentication) success = http.SetSslClientCert(cert) If (success <> True) Then Debug.WriteLine(http.LastErrorText) Exit Sub End If ' At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS ' connection will automatically use it if the server demands a client-side cert. |
