ECC point in projective coordinates (X, Y, Z)

In projective coordinates, the affine point (x, y) is represented as (X, Y, Z) where x = X/Z and y = Y/Z (for standard projective) or x = X/Z² and y = Y/Z³ (for Jacobian projective).

Fields

x: [u8; 66]

X coordinate

y: [u8; 66]

Y coordinate

z: [u8; 66]
