I think I just found a bug in the crypto library on linux.

I was trying to figure out why my program was not working and tracked it down to Crypto.SHA3\_256 returning the wrong result when compared to macOS and an online hash tool.

Am I missing something before I make a report?

**SHA2\_256**

`EncodeHex(Crypto.SHA2_256("test"))`

**macOS 14.2.1** : 9F86D081884C7D659A2FEAA0C55AD015A3BF4F1B2B0B822CD15D6C15B0F00A08

Not yet, just checking if I was missing something.
