This slightly optimizes the NAF function by avoiding returning the
unused bit when there is not a carry.
It also adds a bunch of additional unit tests which I made while
debugging.
This commit contains various modifications for code and comment
consistency in the btcec package:
- Call out references at the top and reference them by their identifier in
the other comments
- Remove a TODO that no longer applies
- Add comments to the fields in the KoblitzCurve struct and reorder them
slightly
- Make comments wrap to 80
- Cleanup code that was far exceeding col 80 (only function declarations
typically do this)
- Extend block comments to use as much of the 80 cols as available
- Add a bit more explanation in a couple of places
- Update copyright year on secp256k1.go
- Fix a couple of typos in the comments
This commit converts the initialization of the constants to use a function
which panics on error instead of just ignoring the error. This is
acceptable since they are hard-coded constants and should never fail.
