About

Anon Aadhaar Core is the cornerstone of the Anon Aadhaar protocol, encompassing all essential TypeScript components needed to interact with our cryptographic circuits. At its heart lies the innovative PCD framework from Zupass, which we leverage for structure and typings.

Key Features:

• Interface of our Circuits: Directly interfaces with the Anon Aadhaar Circom circuits.
• Use of PCD Framework: Utilizes the PCD framework from Zupass for robust data processing.

• init
  • Description: Initializes the Core package with necessary parameters.
  • Usage: init(args: InitArgs): Promise<void>
• verify
  • Description: Verifies the provided AnonAadhaarCore proof.
  • Usage: verify(pcd: AnonAadhaarCore): Promise<boolean>
• serialize
  • Description: Serializes the Anon Aadhaar core object for storage or transmission.
  • Usage: serialize(pcd: AnonAadhaarCore): Promise<SerializedPCD<AnonAadhaarCore>>
• deserialize

  • Usage: deserialize(serialized: string): Promise<AnonAadhaarCore>

The core package also provides helper methods such as:

• generateArgs
  • Description: Generates the arguments to generate a proof, from the scanned QR data and the corresponding certificate file.
  • Usage: generateArgs(qrData: string,certificateFile: string,nullifierSeed: number,signal: string): Promise<AnonAadhaarCore>
• hash
