samuele-andreoli opened a new issue #74: BIG comp is not constant time URL: https://github.com/apache/incubator-milagro-crypto-c/issues/74 The BIG comparison is not constant time. It should use a constant time implementation. For instance ``` /* sodium constant time implementation */ int BIG_XXX_comp(BIG_XXX a, BIG_XXX b) { int i; chunk gt=0; chunk eq=1; for (i = NLEN_XXX-1; i>=0; i--) { gt |= ((b[i]-a[i]) >> BASEBITS_XXX) & eq; eq &= ((b[i]^a[i])-1) >> BASEBITS_XXX; } return (int)(gt+gt+eq-1); } ```
