Set an FTPS Client Certificate from a PFX File

See more FTP Examples

Demonstrates the Chilkat Ftp2.SetSslClientCertPfx method, which loads a client certificate and private key from a PFX/P12 file. The first argument is the file path and the second is its password.

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.

    // key from a PFX/P12 file.  The 1st argument is the PFX file path and the 2nd is its password.

    const ftp = try chilkat.Ftp2.init();

    ftp.setHostname("ftp.example.com");
    ftp.setUsername("myFtpLogin");

    // 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.setPassword("myPassword");

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

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