ProtWare HTML Guardian encryption weakness

by Nikola Strahija on March 29th, 2003 The encryption scheme implemented in ProtWare HTML Guardian is using a simple bit shifting technique, which makes it trivial for attackers to reverse.

ProtWare HTML Guardian version 6.3 and prior to 6.3

Not vulnerable
ProtWare HTML Guardian version 6.4

The latest version implements 384bit key encryption
which is not vulnerable to this flaw.
