Fields
module_id: vector<u8>
Issuing Nitro hypervisor module ID.
timestamp: u64
UTC time when document was created, in milliseconds since UNIX epoch.
digest: vector<u8>
The digest function used for calculating the register values.
pcrs: vector<vector<u8>>

public_key: std::option::Option<vector<u8>>
An optional DER-encoded key the attestation, consumer can use to encrypt data with.
user_data: std::option::Option<vector<u8>>
Additional signed user data, defined by protocol.
nonce: std::option::Option<vector<u8>>
An optional cryptographic nonce provided by the attestation consumer as a proof of authenticity.
