- PASSWORD README NOTES 07/29/89
-
-
- This will be complicated. How's that statement for a program. But it
- has to be complicated for security. Making the Amiga secure is impossible.
- But with work, you can make it complicated enough to discourage anyone from
- being able to boot your system. Actually booting the system is easy, but if
- you set your system up properly using this password program, you will need
- the correct password to obtain full access to the Amiga.
-
- To really install this program correctly, you need to be quite familiar with
- the CLI and your startup-sequence.
-
- This program can be better, but then it loses portability to every Amiga.
- My personal version of the program contains all of my startup-sequence in
- system calls. In fact, even the command to mount my hard-drive is in the
- password program. This way, if someone tries to boot my system without
- knowing the password, they must know how to mount the hard-drive too.
- I've got a few other traps worked out which will be described later.
-
- I have not included the source code to this program like I have with
- everything else I've ever uploaded. This is my most complicated program,
- yet for security reasons, I won't release the source. I have worked out a
- good algorithm for the password encoding and don't want to just give it
- away.
-
- Install the program and change the password. View the password file. It
- looks like a bunch of garbage. Then change the password to something else
- and then back to the original password. View the file again, it's
- different!
-
- Since I wrote the program and am very familiar with CLI and batch files, I
- can think of many ways to get around the program (which I won't totally
- describe). But real knowledge is required to circumvent the program, do
- your kids or wife or friends have this knowledge?
-
- There is a back-door into this program. There is a maintenance password
- that will always work no matter if the user password is known or not.
- This means that if anyone else has these documents, they have the
- maintenance password and access to your computer. See password.doc for
- more information on the maintenance password.
-
- If you want a really secure version (as secure as it can get), you will need
- a custom version for your particular application. Your entire startup-
- sequence needs to be incorporated in the password program using system
- calls. You will also get a unique maintenance password of your choice.
- This can be quite effective if you have a hard-drive and don't auto-boot.
-
- For a custom version of the program send $25 and a blank disk or $30
- without a disk. I will need a copy of your startup-sequence(s) and what
- your want your maintenance password to be. Please include your telephone
- number in case I have any questions about your requirements. I will write
- you a custom version of the program and mail it back to you. If you have
- any questions about this before sending any money, just contact me.
-
- If there is any interest, future releases will be more like the UNIX version
- of passwd. The user will be required to enter a login and then a password.
- This will allow the system administrator (you) to log every persons use
- of the computer by login. Each user will have their own unique changeable
- password. This will provide one more level of security.
-
- Good luck, and feel free to contact me if you need any help getting setup.

- FYI: I recently got divorced and discovered that my wife had been in my
- computer deleting files and gathering information. Although she no
- longer has access to my computer, no one else will ever use my
- computer without my permission or against me....
