             Summary: Add Support for CTR and GCM cipher transformations in AES UDFs
                 Key: HIVE-29392
                 URL: https://issues.apache.org/jira/browse/HIVE-29392
             Project: Hive
          Issue Type: Task
          Components: Hive
            Reporter: tanishqchugh
            Assignee: tanishqchugh


AES UDFs - *aes_encrypt* and *aes_decrypt* currently support only the default AES cipher transformation which is basically AES/ECB/PKCS5P transformation, as it is hardcoded.

ECB mode is inherently weak, as it produces the same ciphertext for identical blocks of plain text.

We intend to make this definition configurable to support other strong CTR / GCM modes.
