FTPS with Mutual TLS Authentication (TLS Client Certificate)

See more FTP Examples

Demonstrates how to do mutual TLS authentication (using a client certificate from a .pfx/.p12). C++

    //  See Global Unlock Sample for sample code.

    //  If using implicit TLS, you probably want port 990..
    ftp.put_Port(990);

    //  Set this to false for implicit TLS, otherwise set to true for explicit TLS (where port is typically 21).
    ftp.put_AuthTls(false);
