Similar question here, are there replacements we can use for it? I also couldn't see it being used in any test other than t0015 when searing for "test-tool sha256". Maybe I'm looking for the wrong thing?

Also, we do have the same test data for both hashes, and if we ever grow another hash it's likely that we'll also want to check for the same inputs there. Would it make sense to have a generic `TAST_HASHES()` macro where you give the input and then both the expected SHA1 and SHA256 to avoid some duplication? Patrick
