I've run across a lot of confusion regarding Activ EBook's password system and how it works. So I thought I'd post some information that might help.
If you want to password protect your Activ EBook you can choose how many password combinations to use ( from 1 to 1000 ). Normally you would set the eBook for 1000 passwords and have Activ EBook use it's built in password generator to make up the password list.
Is a list of only 1000 passwords very secure? Basically when looking at the level of security you need to consider the odds that two people will need the same password. While odds of 1 in 1000 are not great, in reality, you need to consider what the odds are that one person and his next door neighbor, or his best buddy will need the same password. pretty remote...
Can passwords be hacked? While a hacker might be able to discover a password (given a lot of time and motivation), it far more likely that a customer would post his password on the Internet. That still leaves 999 versions fully protected. If you discover any passwords have been leaked, just recompile your eBook with a new list of passwords and the problem is fixed.
How are required passwords determined? When Activ EBook is first installed it looks at a number of hardware or software variables on the host computer (I don't know what) and somehow uses that information to determine a password key for that computer. For a list of 1000 passwords, Activ EBook will determine a specific password key for the computer - a number between 1 and 1000. For example; one computer might need password number (key) 763 and the actual password for number 763 might be H6F3gZ5. (key = 763, password = H6F3gZ5 )
If you distribute a second eBook to the same customer (with a different set of passwords), the customer will still require password number 763 - but for the new eBook the password for 763 might be 7FGj45K
TIP: If your have to reinstall your eBook (after a system crash) and end up at the "Order" page - how do you re-enter your saved password?
At the "Order" page simply press "Crtl K" (the "Ctrl" and "K" keys) and a password entry box will appear.
