I am stuck with a very silly mistake.
I had a problem with my Mikrotik router OS, I simply did a restore for a backup I had done two months ago.
Now I am stuck as my password has also been restored and I cannot remember what my password was at that time.
Any help apart from re-installing the RouterOS again
i wouldn’t give my passwords to some random webpage with very suspicious design 
fully agree
but that password is old password from old backup - it will be changed to new one as soon as he will be able to login, I believe =)
just make sure your old password isn’t something you use elsewhere, for example on paypal
there’s always another, harder and safer, way: open-source software, http://manio.skyboo.net/mikrotik/
Still using pretty weak encryption anno 2011? 
?
why make it stronger? don’t give access to your router to other people, and keep your backup file safe.
It is not always easy to prevent (physical) access.
I’m just saying, in general, it is good pratice to use strong encryption.
The question can easily be stated the other way around: why not use strong encryption?
any kind of encryption can be broken quite easily
Onother silly one,
The backup is still on the router PC, how can I get it out of there. Can I remove the harddisk and connect it externally to my laptop and be able to get it on a Windows machine?
How so? I’m pretty confident you’ll not break the current AES encryption any time soon. Current Linux password storing methods are considered quite safe. So I’m a bit surprised about your comment (and that any kind of encryption can be broken easily is just plain untrue, so you must mean something else I’m missing).
Ok, what I mean is that the backup I need to put in the link provided.
But the problem is that the backup is in the router OS and not in my computer.
So is there a way I can get the backup from the router OS then copy it into my laptop and extract the password.
The router PC is here with me and is working properly after the restore but I cannot log into winbox becoz of password change.
and the winner of RC5-32/12/9 is!..

Normis!!!
he receives $10’000!
you may boot from any Linux LiveCD and mount ROS partition to copy files from it
to encrypt something, we need a key. you would have to provide a password that you would have to remember.
so? this doesn’t help, either the backup file wouldn’t be transferible to other PC, or the potential cracker would just have to find where the key was taken from.
Normis, don’t feign foolishness. if you save only (machine-independent) hash for password - then you cannot just enter it into ‘password’ box (even if you got an access to the router files and read the hash value), you need initial non-hashed password to pass authentication. and if your password is not short - then you need bruteforce attack to restore password from hash. that’s it, hash function is one-way
I’d like the cracker to restore my passwords in weeks, not in seconds
what is your request exactly? to encrypt passwords inside RouterOS, or to make better backup file encryption?
