View Full Version : bug in FGInt lib? (RSA)

February 26th, 2003, 15:06
Ive looked at the FGInt library for delphi (http://triade.studentenweb.org/GInt/gint.html), which implements big num usage for RSA.

it seems that it doesnt encrypt right, c = m ^ e (mod n) isn't calculated correctly.. anyone else noticed this bug ?

if so, where is the bug in it and how can you fix it?

thanks in advance..

Are you sure? NetCaptor also uses FGInt to implement its serial number protection and it works.

Another prog which uses FGInt: FastBrowser Pro.
