FeistelCipher, AshFeistelCipher - Encrypted integer IDs using Feistel cipher

However, the library supports an alternative pattern: Keep id as a sequential primary key and encrypt a separate disp_id column for public display:

Wouldn’t we still want/need a secondary index for disp_id to lookup – assuming growing number of rows – the record on an outside request?

So that’s still more work on top of the serial PK?
