…tion Two new classes of functions for the Wawaka common library: * Secrets -- simplify (and standardize) generating messages that can be shared between contracts; a message is encrypted with the contracts encryption key. * Attestation -- wrappers for the sgx report verification and processing functions Signed-off-by: Mic Bowman <mic.bowman@intel.com>
There are several methods that are common to many contracts. This update provides a base implementation for those methods in order to simplify contract development. Add common contracts methods for attestations Provides a wrapper for managing attested contract endpoints. Contract object provides an attestation package that is verified registering the encryption & verification keys for the contract. Useful for building contracts that share secrets. Signed-off-by: Mic Bowman <mic.bowman@intel.com>
Replace the code in the attestation test with calls packaged in the attestation common contract code. Complete the implementation of the send/recv secret. Complete testing of the new methods. Signed-off-by: Mic Bowman <mic.bowman@intel.com>

Mostly added comments and adjusted permissions on some of the methods in the attestation contract. Changed the code metadata to return the code hash. In theory that change isn't necessary but it does make things easier for some contracts. Signed-off-by: Mic Bowman <mic.bowman@intel.com>

Two new classes of functions for the Wawaka common library:
Add library of common wawaka contract methods.
There are several methods that are common to many contracts. This update provides a base implementation for those methods in order to simplify contract development.
Add common contracts methods for attestations. Provides a wrapper for managing attested contract endpoints. Contract object provides an attestation package that is verified registering the encryption & verification keys for the contract. Useful for building contracts that share secrets.
Update attestation test to use the new helpers. Replace the code in the attestation test with calls packaged in the attestation common contract code. Complete the implementation of the send/recv secret. Complete testing of the new methods.
