If you try to divide the key into a divisor of 66 characters, the program accepts this divisor as a public key.

mark@ubuntu:~/Desktop/ecctools2$ ./keymath 03cd0fdaf5f7503342a20861b15491de59ba31ffe554c42372e4d0926a318cee8e / 963092532556721731126452703333034206412304441762446377444048756866
[E] Some invalid bit in the publickey: 963092532556721731126452703333034206412304441762446377444048756866

Sometimes with this division it gives an error: "We don't know how to divide 2 publickeys, we need an escalar number"
