(Ruby) 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.
require 'chilkat' # 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() # Any string unlocks the component for the 1st 30-days. success = ftp.UnlockComponent("Anything for 30-day trial") if (success != true) print ftp.lastErrorText() + "\n"; exit end ftp.put_Hostname("ftp.***.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.
