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). Lianja

llSuccess = .F.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// If using implicit TLS, you probably want port 990..

// Set this to .F. for implicit TLS, otherwise set to .T. for explicit TLS (where port is typically 21).
loFtp.AuthTls = .F.

// Set this to .T. for implicit TLS, otherwise set to .F..
loFtp.Ssl = .T.
