how about we add

typedef std::array<uint8_t, hashSize> Digest;

here - then we don’t have to use hashSize everywhere. Patch looks good otherwise.

True, yet not really a helpful comment. Nor in the format we use for comments in WebKit.

Right; I wrote that comment when digest.clear() was deleted. Is it better to remove it?

I think it would be slightly better, yes.

There’s no need to export a typedef, and that’s what caused the build failure. Remove this WTF_EXPORT_PRIVATE.
