Module proof 

Functions

build_proof_data

Build proof data: [resource_hash: 32 bytes][proof: 32 bytes].

compute_expected_proof

Compute expected proof: SHA-256(unencrypted_data + resource_hash). unencrypted_data is the same data used in compute_resource_hash.

compute_resource_hash

Compute resource hash: SHA-256(unencrypted_data + random_hash). unencrypted_data is the metadata-prefixed data BEFORE encryption. Returns full 32-byte hash.

validate_proof

Validate proof data against expected proof. proof_data = [resource_hash: 32 bytes][proof: 32 bytes]
