Module ecc

Modules

• ecdsa
• fixed_base
• pippenger

Structs

• EcPoint
• EccChip
• StrictEcPoint
  An elliptic curve point where it is easy to compare the x-coordinate of two points

Enums

• ComparableEcPoint
  An elliptic curve point where the x-coordinate has already been constrained to be reduced or not. In the reduced case one can more optimally compare equality of x-coordinates.

Functions

• check_is_on_curve
  Checks that P is indeed a point on the elliptic curve C.
• ec_add_unequal
  If is_strict = true, then this function constrains that P.x != Q.x. If you are calling this with is_strict = false, you must ensure that P.x != Q.x by some external logic (such as a mathematical theorem).
• ec_double
  Assumptions
• ec_double_and_add_unequal
  Implements: computing 2P + Q = P + Q + P for P = (x0, y0), Q = (x1, y1)
• ec_select
• ec_select_by_indicator
• ec_select_from_bits
• ec_sub_strict
  Constrains P != -Q but allows P == Q, in which case output is (0,0). For Weierstrass curves only.
• ec_sub_unequal
  If is_strict = true, then this function constrains that P.x != Q.x. If you are calling this with is_strict = false, you must ensure that P.x != Q.x by some external logic (such as a mathematical theorem).
• get_naf
• into_strict_point
• load_random_point
• multi_scalar_multiply
  Assumptions
• scalar_multiply
  Computes [scalar] * P on short Weierstrass curve y^2 = x^3 + b
• strict_ec_select_from_bits
