Replacing struct SignEnclaveInfo with trait PcrSigner allows us to support new signing methods by extending trait PcrSigner without changing the existing code.
Add struct PrivateKeyPcrSigner for signing PcrInfo with PrivateKey
Add fn get_measurements, struct PcrCoseSign1 and struct SignaturePcrSigner. For security reasons, the private key is usually in a separated environment, so it may not be possible to build an enclave with private key in a single step from the building pipeline. Inspired by Digest Signing in oesign,
fn get_measurements is used to generate measurements without writing output enclave image file.
struct PcrCoseSign1 is exported to public and provide function to sign PcrInfo
struct SignaturePcrSigner is used to accept the signature, verify it, and directly write it to the enclave image file.
