I applied the patch to gpg source and compiled as recommended in the loop-AES.README. Appears to work ok. Is there any easy way to tell if iteration actually has been "slowed down by 128 times" ie that the patched gpgp is working as it should? __________________________________________________ Do You Yahoo!?
