get_b

Returns the Weierstrass ‘b’ parameter for a given curve.

For Weierstrass curves: y² = x³ + ax + b

Arguments

• curve_index - Index of the curve (0-5)

Returns

• The ‘b’ parameter as u384, or zero for invalid indices

Note

For ED25519 (index 4), this returns the ‘b’ parameter of the birationally equivalent Weierstrass curve, not the Edwards curve parameter.
