> https://github.com/apache/spark/pull/32801 added aes_encrypt/aes_decrypt
> functions to spark. However they rely on the jvm's configuration regarding
> which cipher mode to support, this is problematic as it is not fixed across
> versions and systems.
> Let's hardcode a default cipher mode and also allow users to set a cipher
> mode as an argument to the function.
> In the future, we can support other modes like GCM and CBC that have been
> already supported by other systems:
> # Snowflake:
> https://docs.snowflake.com/en/sql-reference/functions/encrypt.html
> # Bigquery:
> https://cloud.google.com/bigquery/docs/reference/standard-sql/aead-encryption-concepts#block_cipher_modes
