Max Gekk created SPARK-37666:
--------------------------------
Summary: Set `GCM` as the default mode in
`aes_encrypt()`/`aes_decrypt()`
Key: SPARK-37666
URL: https://issues.apache.org/jira/browse/SPARK-37666
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.3.0
Reporter: Max Gekk
Assignee: Max Gekk
Change the default mode from ECB to GCM in AES functions: aes_encrypt() and
aes_decrypt(). GCM is much more preferable because it is semantically secure.
Also the mode is used the default one in other systems like Snowflake, see
