-/**
- * A Sync crypto record has:
- *
- * <ul>
- * <li>a collection of fields which are not encrypted (id and collection);</il>
- * <li>a set of metadata fields (index, modified, ttl);</il>
- * <li>a payload, which is encrypted and decrypted on request.</il>
- * </ul>
- *
- * The payload flips between being a blob of JSON with hmac/IV/ciphertext
- * attributes and the cleartext itself.
- *
- * Until there's some benefit to the abstraction, we're simply going to call
- * this <code>CryptoRecord</code>.
- *
- * <code>CryptoRecord</code> uses <code>CryptoInfo</code> to do the actual
- * encryption and decryption.
