Excel password cracker (97/2000/xp) Very simple spec. Develop a program which extracts the hashes, any other necessary information directly from an Excel file and do a brute force attack on them in order to find the password. If you are unsure what is meant by this I do not think you will be the right person for the job. This really needs someone familiar with the specifics of the encryption used here. I have developed a dictionary/brute force cracker that is, predicatbly, very slow. This has been developed in VB.NET, not VBA but is still too slow to be practical. I'm intereseted in hearing other views on how to approach this but really feel the only viable approach is to work on just the hashes. The process of feeding passwords into the system is not the bottleneck. It is the asking Excel (through automation) to open a file and trapping the resulting error. Code has to be intergratable with existing .NET infrastructure. Given the task nature I don't mind C++/C# as it's arguably a better choice for this sort of thing but would prefer VB.
