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. Ruby

require 'chilkat'

success = false

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

cert = Chilkat::CkCert.new()

# Load the certificate from the Windows certificate store
success = cert.LoadByCommonName("my_cert_common_name")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

# Get the private key.  
privKey = Chilkat::CkPrivateKey.new()
success = cert.GetPrivateKey(privKey)
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

privKeyPem = privKey.getPkcs8Pem()
if (privKey.get_LastMethodSuccess() == false)
    print privKey.lastErrorText() + "\n";
    exit
end

sshKey = Chilkat::CkSshKey.new()
success = sshKey.FromOpenSshPrivateKey(privKeyPem)
if (success == false)
    print sshKey.lastErrorText() + "\n";
    exit
end

# Connect to an SSH/SFTP server
sftp = Chilkat::CkSFtp.new()
success = sftp.Connect("sftp.example.com",22)
if (success == false)
    print sftp.lastErrorText() + "\n";
    exit
end

# 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() + "\n";
    exit
end

print "OK, the connection and authentication with the SSH server is completed." + "\n";

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