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.

    var success: Bool = false

    //  Demonstrates the Imap.SetSslClientCertPem method, which supplies a TLS client certificate
    //  and private key from PEM.  The 1st argument is the PEM text or a PEM file path, and the 2nd
    //  is the password when the private key is encrypted.  It must be called before connecting.

    imap.ssl = true
    imap.port = 993

    //  The PEM private-key password is not hard-coded in source.  Insert code here to obtain it from an
    //  interactive prompt, environment variable, or a secrets vault.
    var pemPassword: String?

    //  Provide the PEM client certificate BEFORE connecting.  The first argument may be a PEM file
    //  path or the PEM text itself.
