Generate Proof

Prerequisites

Before using the Generating Proof Endpoint, There are three essential items you'll need to use the endpoint:

1. encryptedUserDataToken : This token contains your encrypted user data

2. encryptedDvrToken : This token holds your encrypted DVR data

3. apiToken : This unique identifier authenticates your requests with the zkPass API

apiToken is the base64 form of YOUR_API_KEY:YOUR_API_SECRET.

Generating Encrypted Tokens:

For instructions on creating the encryptedUserDataToken and encryptedDvrToken, refer to our Utilities section. It provides a step-by-step guide that covers:

1. Generating a Key Pair: This creates the keys you'll use for signing your data.

2. Signing User Data and DVR: This step adds a digital signature to your data tokens, ensuring their authenticity.

3. Encrypting User Data and DVR: This encrypts your data tokens, making them unreadable by anyone without the decryption key.
