The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Matching C++ encryption/decryption with C#

Asked by SutherlandsW in Encryption for Network Security, C Programming Language, C# Programming Language

Tags:

I'm trying to create two programs, one in C# and one in C++ that decrypt a given encrypted password and return it.  I know that external libraries would do this just fine, but we're trying to use the MSDN Encryption API.  The problem with that is that you can't just specify a key like you can in C#.  In C# you can use RijndaelManaged and set the IV, key, and pass in the bytes and I've gotten the correct result that way with a test vector.  With C++, I can do no such thing as setting the bytes.  The only way to generate a static key based without having another key is to use the CryptDeriveKey function, which takes in data from a HCRYPTHASH parameter.  Well, I have no idea what's being done to the data and no way to get it out (the windows CSPs don't allow access to the key or allow you to set it unless it's DES).  Start Free Trial
