Michael Hamburg	f8dc967ae1	add explicit GF_HEADROOM per field+arch for unreduced arith; fortunately unreduced arith is very rare	9 years ago
Michael Hamburg	a585d7f148	factor out elligator, decaf, scalar code. scalar_halve is now public	9 years ago
Michael Hamburg	790745e2b3	set mulw to <32 bits instead of <64 bits (but actually less than that: 1 limb instead of 2). also there is a bug if you compile ed448 for arch_32 on a 64-bit machine... tracing	9 years ago
Michael Hamburg	4de70b837c	separate out strobe and spongerng from shake. strobe is experimental. spongerng is experimental internally but the interface should be pretty good (except for any camelCase vs snake_case issues). shake should be stable	9 years ago
Michael Hamburg	825751d034	one gf_strong_reduce to rule them all	9 years ago
Michael Hamburg	38455f34f2	one ser/deser to rule them all (TODO test on NEON and other places with LIMBPERM)	9 years ago
Mike Hamburg	a5bed6b351	Working on getting cross-arch working again. Several TODOs. Currently compiles and passes tests on x86_64 with arch_32 and DECAF_FORCE_32_BIT=1 (as well as the native settigs of course), so that's a start. Want to make serialization routine cross-arch. Need to check that perf is good enough (likely). Current routine in p25519/arch_32 is almost cross-arch, but has known bugs (FIXMEs). Needs to take into account separate p and, for NEON, the LIMBPERM. Want to decouple arches for each curve/field. Currently the split between decaf_word_t and word_t makes this fraught with peril. Fix is probably to rename decaf_word_t to decaf_api_word_t and fix it to either uint32 or uint64, then make internal things separate per field. That way we don't have to try arch detection in the header, which is nice. Need to make decaf_gen_tables use SC_LIMB. Might as well get rid of API_NS there too.	9 years ago
