Mathcad Password

Mathcad Password

I realize this is off topic but I am running out of places to search for an answer...

I have an area in a mathcad sheet that is passworded so it cannot be expanded.
This password has been lost.
Does anyone know any way for me to figure out that password?
I know in old mathcad versions the password had been saved in the file but as far as I can tell that is no longer true.
I also know I could write my own brute force script.
I am hoping to at least figure out how to get the encrypted gzip file out of the mathcad file so I can use brute force software already developed. Any idea how to do this would be appreciated.

Any other ideas would also be greatly appreciated.

Depending on how the worksheet has been protected, I may be able to open the area. I will not tell you how to do so though, even privately.

I would also only be prepared to do so if you could prove to me that you have rights to the IP that may be in the collapsed area.

Well let me ask some simple questions at least.

What are the different ways a mathcad sheet can be protected?

Maybe you can at least tell me if your method is just brute force or something different- perhaps more elegant.

Look in the help, under "protecting your worksheets".

If by "brute force" you mean some password guessing game, no.

If you have Mathcad 14 and have password protected an area, we did made the password garbled, so that it could not be easily retrieved. I believe it was easy to break in older versions of Mathcad.

Unfortunately for you, that is the purpose of having password protection.

There may be some way of finding the password, but we are unaware of it.
