Classic ASP Requires Chilkat v10.1.2+

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

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.

'  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
'  

set ftp = Server.CreateObject("Chilkat.Ftp2")

ftp.Hostname = "ftp.example.com"
ftp.Port = 21

'  This example will use explict TLS/SSL.
'  Establish an explicit secure channel after connection
'  on the standard FTP port 21.

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

'  Create an instance of a certificate store object, load a .p12 file,
'  locate the certificate we need, and use it for signing.
'  (a P12/PFX file may contain more than one certificate.)
set certStore = Server.CreateObject("Chilkat.CertStore")
'  The 1st argument is the filename, the 2nd arg is the 
'  .p12 file's password.  (OpenSSL will prompty you to set a password
'  when converting the .crt and .key into a .p12).
