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.
#  See Global Unlock Sample for sample code.

#  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
#  

ftp = Chilkat::CkFtp2.new()

ftp.put_Hostname("ftp.example.com")
ftp.put_Port(21)
ftp.put_Username("testLogin")
ftp.put_Password("testPassword")

#  This example will use explict TLS/SSL.
#  Establish an explicit secure channel after connection
#  on the standard FTP port 21.
ftp.put_AuthTls(true)

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

#  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.)
certStore = Chilkat::CkCertStore.new()
#  The 1st argument is the filename, the 2nd arg is the 
#  .p12 file's password.  (OpenSSL will prompty you to set a password
