3. Generating the Proof

Calling zkPass Service's generate_zkpass_proof REST API to create the ZkPass Proof

To generate the ZkPass Proof, the Data Holder needs to use the zkpass-client SDK library. The following section illustrates how the coding is done.

zkPass-client Integration

The Data Holder generates the proof by using the zkpass-client SDK library, as shown here.

data_holder.rs

...

//
// Step 1: Instantiate the zkpass_client object.
//
let service_url = "https://playground-zkpass.ssi.id/proof";
let api_key = ZkPassApiKey {
    api_key: "5ecb2229-ddee-460e-b598-a0001c10fff1".to_string(),
    secret_api_key: "074a53a8-a252-45de-a9d5-0961a6362df6".to_string(),
};
let zkpass_client = ZkPassClient::new(service_url, api_key);

//
// Step 2: Call the zkpass_client.generate_zk_pass_proof
//         to get the zkpass_proof_token.
//
let proof = zkpass_client
    .generate_zkpass_proof(&user_data_token, &dvr_token)
    .await
    .unwrap();
