SFTP use Cert's Private Key for Authentication (Windows)

See more SFTP Examples

Demonstrates how to use the private key of a pre-installed certificate (on Windows) for SFTP authentication. The certificate's private key must be marked as "exportable" when originally installed. CkPython

import sys
import chilkat

success = False

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

cert = chilkat.CkCert()

# Load the certificate from the Windows certificate store
success = cert.LoadByCommonName("my_cert_common_name")
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

# Get the private key.  
privKey = chilkat.CkPrivateKey()
success = cert.GetPrivateKey(privKey)
if (success == False):
    print(cert.lastErrorText())
    sys.exit()

privKeyPem = privKey.getPkcs8Pem()
if (privKey.get_LastMethodSuccess() == False):
    print(privKey.lastErrorText())
    sys.exit()

sshKey = chilkat.CkSshKey()
success = sshKey.FromOpenSshPrivateKey(privKeyPem)
if (success == False):
    print(sshKey.lastErrorText())
    sys.exit()

# Connect to an SSH/SFTP server
sftp = chilkat.CkSFtp()
success = sftp.Connect("sftp.example.com",22)
if (success == False):
    print(sftp.lastErrorText())
    sys.exit()

# Authenticate with the SSH server using a username + private key.
# (The private key serves as the password.  The username identifies
# the SSH user account on the server.)
success = sftp.AuthenticatePk("mySshLogin",sshKey)
if (success == False):
    print(sftp.lastErrorText())
    sys.exit()

print("OK, the connection and authentication with the SSH server is completed.")

# This example is only to show the connection + authentication using a private key associated with a certificate in the Windows certificate store...
