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.

success: Integer;
imap: TChilkatImap;
pemPassword: WideString;

success := 0;

//  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 := TChilkatImap.Create(Self);

imap.Ssl := 1;
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.

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