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<sui::nitro_attestation::PCREntry>

A list of PCREntry containing the index and the PCR bytes. .

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.

Constants

Error that the feature is not available on this network.

const ENotSupportedError: u64 = 0;

Error that the attestation input failed to be parsed.

const EParseError: u64 = 1;

Error that the attestation failed to be verified.

const EVerifyError: u64 = 2;

Error that the PCRs are invalid.

const EInvalidPCRsError: u64 = 3;

Function load_nitro_attestation

@param attestation: attesttaion documents bytes data. @param clock: the clock object.

Returns the parsed NitroAttestationDocument after verifying the attestation, may abort with errors described above.

Function pcrs

Returns a list of mapping PCREntry containg the index and the PCR bytes.
AWS supports PCR0-31. Required PCRs (index 0-4 & 8) are always included regardless of their value. Additional custom PCRs (index 5-7, 9-31) are also included if they are nonzeros.
