Set an IMAP TLS Client Certificate from PEM

See more IMAP Examples

Demonstrates the Chilkat Imap.SetSslClientCertPem method, which supplies a TLS client certificate and private key from PEM. The first argument may be the PEM text itself or a path to a PEM file (Chilkat detects which), and the second is the password used when the private key is encrypted. Call it before connecting.

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

Background: PEM is the Base64 text format (delimited by -----BEGIN----- lines) commonly produced by OpenSSL and used across Unix tooling. This method is the convenient choice when your client certificate and key already live in a .pem file; use SetSslClientCertPfx for a PKCS #12 .pfx/.p12 bundle instead.
