* Warn user supplying nonce values in FIPS mode for transit encryption requests
- Send back a warning within the response if an end-user supplies nonce
values that we use within the various transit encrypt apis.
- We do not send a warning if an end-user supplies a nonce value but we
don't use it.
- Affected api methods are encrypt, rewrap and datakey
- The warning is only sent when we are operating in FIPS mode.
Decrypting an ciphertext where its corresponding value equals empty, the payload property "plaintext" is missing in the response object. This fixes the problem by adding a new, distinct struct for decrypt batch response items where "omitempty" is not set.
