Upload to Tumbleweed SecureTransport FTPS Server

See more FTP Examples

Demonstrates how to connect, authenticate, and upload file to a Tumbleweed Secure Transport SSL FTP Server. Instead of providing a login name and password, you pass the string "site-auth" for the username, and an empty string for the password. You must also provide a client-side digital certificate -- as the certificate's credentials and validity are used to authenticate. CkPython

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

ftp = chilkat.CkFtp2()

# This code has been tested with the Tumbleweed server
# at sft.wellsfargo.com
ftp.put_Hostname("sft.wellsfargo.com")

# Use these exact strings for the username and password:
ftp.put_Username("site-auth")
ftp.put_Password("")

# Establish an AUTH SSL secure channel after connecting.
# Your client-side certificate is used for authentication when
# the SSL channel is established.
ftp.put_AuthSsl(True)

# The Ssl property is for establishing an implicit SSL connection
# on port 990.  Do not set it.
ftp.put_Ssl(False)

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

success = certStore.LoadPfxFile("my.pfx",password)

# Tell the Chilkat FTP2 component to use the client-side
# cert for the SSL connection:

# Connect and authenticate with the FTP server.

# Change to the remote directory where the file will be
# uploaded.  If your file is to be uploaded to the FTP user 
# account's home directory, this is not necessary.
