Henry de Valence	e17c98a391	Ensure NAF works on manually-constructed extremal values. ... The NAF computation can generate a 1 in the last digit (only) when s = 2^255-1, so someone who manually constructed the value s = 2^255-1 and fed it into a NAF-using computation could generate an incorrect result. Some version of this bug has been present from the beginning of the library, but it has no security content, because the NAF computations are not applied to secret data, and the error occurs only on one value which is not constructed by any client caller.	2019-06-05 23:18:43 -07:00
Henry de Valence	f1d2b5182b	Restructure source tree into serial and vector backends. ... This begins to attempt to restructure the source tree so that the common parts are common and the different parts are different. The backend is now split into two parts: - serial (containing the implementation using serial formulas and mixed-model arithmetic). - vector (containing the implementation using parallel formulas and single-model arithmetic). The serial scalar_mul tree is now under backend::serial::scalar_mul. The avx2 scalar_mul tree is now under backend::avx2::scalar_mul.	2019-01-18 01:49:40 -08:00
