This is a types-only change.
crypto.timingSafeEqual
has some subtle behavior (highlighted in bold red in the docs!) when passing aFloat32Array
orFloat64Array
. Rather than adapt our wrapper to support this unusual situation, this updates the types to avoid it.We never took advantage of this unusual case, and now we are even less likely to.
I plan to yolo-merge this if CI passes.
