Set a TLS Client Certificate for IMAP

See more IMAP Examples

Demonstrates the Chilkat Imap.SetSslClientCert method, which supplies a client certificate for TLS client-certificate authentication. The only argument is a Cert object that must provide access to its private key. Call it before connecting. This example loads the certificate from a PFX file.

Note: The certificate path is relative to the application's current working directory. Supply the path to your own certificate file.

Background: Most IMAP servers authenticate with a username and password only. A few high-security deployments additionally require mutual TLS, where the client presents its own certificate during the handshake. Because that happens as part of connecting, the certificate must be set before Connect — setting it afterward has no effect on the already-established connection.
