Demonstrates how to get a Google Drive API access token using a .p12 private key. C#

bool success = false;

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

// Choose a scope.

// Request an access token that is valid for this many seconds.

// If the application is requesting delegated access:

// then set the email address here. (Otherwise leave it empty.)

// Connect to www.googleapis.com using TLS (TLS 1.2 is the default.)
// The Chilkat socket object is used so that the connection can be established
// through proxies or an SSH tunnel if desired.
