[exelist] Re: PE Encryption Code

[Bluefish <11a@...>]

In order to stop common 'cracking', the randomly generated encryption
algorithms used by various tools seems to provide what you are asking for
(experts, give examples ;-)

This "key" talk seems to be pointing at is strong cryptography, which is
impossible to provide without user giving key before executation, which is
AFAIK outside the field of exelist. Using a strong algorithm using
different keys for each executable (where key would be stored in 
executable) is probably even a lot easier to crack than the polymorphic
encryptions offered by various tools.

Papers/code on polymorphic encryption should be available at most sites
dealing with "anti-cracking" protectors or viruses.

Anyway, executables demanding users to enter passwords is a REALLY sucky
idea which all (real) security experts condem, because it is like asking
to get a trojan. PGP and similar tools would be a more suitable solution
to such tasks.
