Demonstrates sending a request to the bitzlato.com whoami endpoint using an ES256 JWT token for authentication. Rust

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

//  Use the following ECC key loaded from JWK format.

// Now build the JWT claims (also known as the payload)

// Set the timestamp defining an expiration time (end time) for the token
// to be now + 1 hour (3600 seconds)
let _ = claims.add_int_at(-1, "exp", cur_date_time + 3600).is_ok();
