(Tcl) Secure FTP with Client Certificate

Chilkat FTP2 provides the ability to use a client certificate with secure FTP (implicit or explicit SSL/TLS). This example demonstrates how to load a certificate from a .pfx and use it as the client-side SSL cert. Note: Client-side certificates are only needed in situations where the server demands one.

load ./chilkat.dll

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

set ftp [new_CkFtp2]

CkFtp2_put_Hostname $ftp "ftp.***.com"
CkFtp2_put_Port $ftp 21
CkFtp2_put_Username $ftp "test"

# This example will use explict TLS/SSL.
# Establish an explicit secure channel after connection
# on the standard FTP port 21.
CkFtp2_put_AuthTls $ftp 1

# The Ssl property is for establishing an implicit SSL connection
# on port 990.  Because this example uses explicit SSL, it 
# should remain 0.

# Load a certificate from a .pfx
# A PFX may contain several certs, including the certificates
# in a chain of authority.
