I'm trying to maximize my excel addin security. My research indicates an
Excel 2003 VBA password may be a max of 32 characters and the password may
include letters (not sure if upper and lower case are considered different),
numbers, keyboard special characters and spaces.

Does a complex excel VBA password (i.e. 32 char long and many types of char)
provide more security against the password recovery tools?

I thought the recovery tools have different algorithms.
- One algorithm is a brute force match which may take a long time (days or
weeks ?) to match a complex password.
- Another algorithm is to remove the password and replace it with something
else. A complex password would have limited value in this algorithm. I
would also expect this recovery tool to succeed or fail quickly.

Please provide any other suggestions you may have for improving an addin
security.

thanks.
