Default odd or even

Let a= 3
and n large numbre like RSA-260


Code:
22112825529529666435281085255026230927612089502470015394413748319128822941402001986512729726569746599085900330031400051170742204560859276357953757185954298838958709229238491006703034124620545784566413664540684214361293017694020846391065875914794251435144458199
then
x private key
c= ax mod n


we can check if x number is odd or even

We can use just a,n,c to determine if x number is even or odd.

Last fiddled with by LaurV on 2020-09-03 at 07:20 Reason: added code tag for the number - that long line makes the post looks very bad in some browsers
