Client Certificate in REST (USB Token or Smartcard)

See more REST Examples

Demonstrates how to use a client certificate with a REST connection where the certificate and private key are located on a USB token or smart card. Objective-C

// See Global Unlock Sample for sample code.

// This example shows how to use the Chilkat socket object's connection.
