-// Status indicates whether an operation completed successfully, or with an
-// error. The error is used for verification in unit-tests, as well as for
-// display to the user.
-//
-// As such, it is important that errors DO NOT reveal any sensitive material
-// (like key bytes).
-//
-// Care must be taken with what errors are reported back to blink when doing
-// compound operations like unwrapping a JWK key. In this case, errors
-// generated by the JWK import are not appropriate to report since the wrapped
-// JWK is not visible to the caller.
