Remarks
When passed into getSupplementaryAttestationInfo, getSupplementaryAttestationInfo returns the DER-encoded structure corresponding to the `Modules` schema described in the KeyMint HAL's KeyCreationResult.aidl. The SHA-256 hash of this encoded structure is what's included with the tag in attestations. To ensure the returned encoded structure is the one attested to, clients should verify its SHA-256 hash matches the one in the attestation. Note that the returned structure can vary between boots.
