comment Example of Projective Coordinates
+1 for the AI translation of the comment: "If z = null or z = 0, then the value Z becomes 1", which is better than the code is.

comment Cycling hashing in PBKDF's and their limitations in strength?
Why this complex (and evolving) generation of Output (currently Output := E(Hash(PassHash),Salt) | PassHash ) rather than just Output := PassHash ?

comment Convert projective to affine coordinates in ECC?
$(x_3,y_3,z_3)$ is not three points, it's a triplet for the coordinates of one point in protective coordinates. $\;$ Then the answer to the question seems to be clearly given in the paragraph with the two bullets. Are you having a problem understanding what is meant by $X/Z$ in the question? That's $X$ times $1/Z$; where $1/Z$ is the inverse of $Z$ in the base group (e.g. $Z^{-1}\bmod p$ as obtained using the extended Euclidian algorithm when working with base group $\mathbb Z_p$), of the same nature as $X$, $Y$ or $Z$ are; and times is multiplication in the base group.
