I have the backup file of the Sonicwall TZ210 but lost the admin password.
The backup file is .exp, is there a way to decode it using windows pc?
This is not a complete solution, but a start. With Linux, you can use this to decode the dump:
Or use this Perl Script:
You will find the password line and might be able to brute-force it with john the ripper (http://www.openwall.com/john/). There is no easier way here.
