Xbase++ Requires Chilkat v10.1.2+

Using WS_FTP Self-signed Certificate file (.crt) and Private Key File. (.key)

See more FTP Examples

Demonstrates how to use a self-signed certificate created by WS_FTP with Chilkat FTP2.

Note: It is usually not necessary for the FTP client to use a client-side certificate. Most FTP servers using SSL and TLS connections (explicit or implicit) do not require client-side certs. In addition, some high-security FTP servers require "real" certificates -- meaning certificates issued by a real certificate authority with a chain of authentication that leads to a trusted root certificate. The certificates created by WS_FTP are self-signed and untrusted.

//  This example requires the Chilkat API to have been previously unlocked.

//  Important:  Before running this program, convert your
//  .crt and .key files to a .p12 using OpenSSL:
//  The command is this:
//  openssl pkcs12 -export -in test.crt -inkey test.key -out test.p12

//  on the standard FTP port 21.
