how to calculate keccak256 hash in huff code?

[Vincent71399]

I was trying to convert a simple contract with a mapping(address->uint256) storage, but it seem huff does not have a keyword keccak256 like evm, anyone know how to resolve it?

You will need the foundry-huff and huffmate libraries to implement that kind of logic in Huff, I think. That is what we used in the assembly--evm-opcodes-and-formal-verification-course at least when we were implementing HorseStoreV2
