So, I'm confused about what you actually mean by "big endian" here. I originally assumed that you meant that SHA1's are defined as bit arrays, and that the first bit of the SHA1 is in the high-order bit of the first byte. But if you just meant that the first byte of the SHA1 is stored in the first byte of the array... that kind of goes without saying, doesn't it?

In any case, maybe this is a detail that's best left to the code itself.
