@pcd/halo-nonce-pcd

A PCD wrapper for one operation of the HaLo (Hardware Locked) tags from Arx Research, sign_random. This is an operation in which the private key in slot #2 of the HaLo tag produces an secp256k1 ECDSA signature of an incrementing nonce concatenated with a random string. The nonce is incremented by the HaLo tag after each signature operation. These tags can be used to produce in-person PCDs for mementos or baton experiences.
