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.

success: Integer;
ftp: TChilkatFtp2;

//  Demonstrates the Ftp2.SetSslClientCertPem method, which configures a client certificate and

//  private-key password (empty when the key is not encrypted).

ftp := TChilkatFtp2.Create(Self);

ftp.Hostname := 'ftp.example.com';
ftp.Username := '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.Password := 'myPassword';

//  Use explicit FTPS (AUTH TLS) on the standard FTP port.
ftp.AuthTls := 1;

//  Provide the PEM client certificate before connecting.  The password should come from a secure
//  source rather than being hard-coded.
pemPassword := 'myPemPassword';
