Scalar arithmetic #13

Closed str4d closed 5 years ago

str4d commented 5 years ago

Includes 29-bit arithmetic ported from curve25519-dalek, which we use for addition, subtraction, and decoding / reduction.

Multiplication and multiply-and-add use the existing arithmetic extracted from ed25519-java, as it is over twice as fast.
