05:31 < sipa> for constant time ec mult, why don't we use cheap negation to reduce the precomp table?
05:33 < sipa> write the scalar as groups of 5 bit, as an integer between -15 and +15
05:35 < sipa> and then use constant time lookup in the table to find the precomputed G multiple, and then in constant time negate it based on the sign, and add
05:35 < sipa> we do that for ECDH, but i don't think we do for ecmult_gen
05:36 < sipa> (can't check the code right now, maybe i just misremember)
