The parsec/cca package provides the following features:

• Decode and validate a CBOR-encoded Parsec CCA Key Attestation buffer;
• Verify the CCA token using the supplied CPAK public key;
• Verify the binding between the key and platform tokens;
• Provide access to all the claims in both the key and platform tokens.
