ShardingSphere Encryption based on conditional value from another column

[honweng]

I have a table that is used to store data across different tenants with a specific column in the same table used as the tenancy-discriminator.

We will have a new tenant with requirement for certain columns to be encrypted.

May I know if there are any mechanism that we can use to only encrypt/decrypt based on value from another column? Which class should I look at / override for this?

What other implementation would be applicable in my case? Should I explore Sharding strategy and combine that with encrypt?

TIA.
