-----------------------------------
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.
