Set an FTPS Client Certificate from PEM

See more FTP Examples

Demonstrates the Chilkat Ftp2.SetSslClientCertPem method, which configures a client certificate and private key from PEM. The first argument may be the PEM text or a PEM file path, and the second is the private-key password (empty when the key is not encrypted).

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

func chilkatTest() {
    var success: Bool = false

    //  Demonstrates the Ftp2.SetSslClientCertPem method, which configures a client certificate and
    //  private key from PEM.  The 1st argument is the PEM text or a PEM file path, and the 2nd is the
    //  private-key password (empty when the key is not encrypted).

    //  Normally you would not hard-code the password in source.  You should instead obtain it
    //  from an interactive prompt, environment variable, or a secrets vault.
    ftp.password = "myPassword"

    //  Use explicit FTPS (AUTH TLS) on the standard FTP port.
    ftp.authTls = true

    //  Provide the PEM client certificate before connecting.  The password should come from a secure
    //  source rather than being hard-coded.
