Description

Hi,

I'm having an issue testing 2.0.206 with the following query:

select 
encrypt('AES', '00', stringtoutf8('3fabb4de8f1ee2e97d7793bab2db1116')), 
cast(hextoraw(rawtohex(encrypt('AES', '00', stringtoutf8('3fabb4de8f1ee2e97d7793bab2db1116')))) as raw)

I expect the same byte arrays as result, but instead I receive different ones. I'm trying to find a way to make use of encrypt/decrypt as the return types of these functions changed to bytes and I need functions for storing into a varchar column.

Research direction

Reproduce the query from the issue against H2 2.0.206 and compare the byte-array results from ENCRYPT, RAWTOHEX, and HEXTORAW. Read the implementations and tests for these functions to determine whether the conversion is expected to preserve bytes. Done means the round trip produces the same bytes and supports the stated varchar-storage use case.
