- Act! v2 for Windows
-
- Act! was written by Symantec, a company that really should have known better. Act! does not actually encrypt data at all. Instead,
- it merely stores the password in encrypted format, and asks you to enter the password before it lets you see the database. Not
- terribly effective.
-
- The obvious solution is to create a database of your own and save it. Save it again under a different name, but this time with a
- password. Doing a file compare, you should see only a few changes. All but one will be obvious changes, ie, the name of the file. In
- one file, filename.MUD, you will see two double-quotes in the 'unencrypted' file, and two double-quotes with junk between them in
- the 'encrypted' file. You're almost there already.
-
- You have two ways to proceed at this point - change the password, or decrypt the original password. We'll start with changing the
- password. In the same location (Offset, anyone?) in the *.MUD file you wish to crack, you'll find a set of double-quotes. Actually,
- you'll find three. Of the three, only one will have eight or less characters between the quotes. All you have to do is change the first
- junk character to a double-quote (to make a set of empty quotes) and fill the rest of the field with the empty 2Eh character. A good
- hex-editor will come in handy here.
-
- The other possibility is to decrypt the password. Its a simple substitution code, thus it'd be simple to write a program to automate the
- process. I'm too lazy, any takers?

- All those values are hexadecimal, of course. Anyone who cares to look up the punctuation is free to, but nobody uses punctuation
- anyway.

- Any information about other versions of Act! is welcome.... To the best of my knowledge, versions 1 and 3 have the same flaws.
