I have made a small tool that is using bruteforce to decode passwords.
Using these chars: A..Z + a..z + 0..9 + 5 additional chars - a total of 65
chars.
It finds passwords with 3 chars in a maximum of 6 seconds.
Passwords with 4 chars are found in a maximum of 8� minute.
5 chars are estimated to take quite a long time, but possible...

In your case I think you should spend a weekend restoring the latest backup
into a database, changing the password for the superusers and then replace
the database with your newly created database. Otherwise you could wait
forever for a solution... If the database it to big you could consider
contacting Microsoft - they can grant you full access to the running
database enabling you to reset the password of the superuser. (only version
4SP? or earlier)

/Peter

PS: The tool was simply made for proof-of-concept purposes and is not
shared. Sorry...

It is a total of 67 chars - hHopefully my coding is better than my counting
:-)

5 chars should then take 67 time longer, which is 9� hour
6 chars should then take 26� days
7 chars should then take almost 5 years.
And so on...

PS: Not tested ;-)

Is it possible, and how, to decrypt an encrypted Navision password?

I have restored an old Navision database backup, so I know the
encrypted passwords (by copying the user data to excel), but now I
want to know the real passwords again.
I need this, so I can login again with a super user in the live
database.

I have 2 examples of encrypted passwords: ~N����O.&a and ~����72��~

Regards,
Ernesto

From w1w1ism.pdf "Installation & System Management: Navision Attain Database
Server" (page 115) - DocID: AT-360-ING-001-v01.00-W1W1

"If you forget your password or user ID, you will be allowed an unlimited
number of attempts to enter it. You can also request a new password from a
user who has permission to change other people's passwords.
If all users have forgotten their user IDs or passwords (passwords are
encrypted, so they cannot be seen anywhere in the program), so no one can set
up new ones, you can get a special password from your Navision Solution
Center (NSC). Follow this procedure:
1 Open Navision Attain.
2 When the Login window appears, enter ??????????... (20 question marks) as
the
user ID. The program now displays a window containing a code.
3 Give the code to your NSC, and they can supply you with a new password.

Warning
.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
.. . .
Do not use the keyboard or mouse before you enter the new password.
4 Enter the password from the NSC. It can only be used once.
5 Click OK to close the window.
6 As soon as you have entered it, click Tools, Security, Users, and set up
your own
password."
