I need a class to encrypt and decrypt strings.
I need TWO VERSIONS of the class, one for Visual C++ and the other written in LotusScript.
What is LotusScript?
LotusScript is a Lotus Notes scripting language which is very similar to Visual Basic 6 – it’s 95% compatible with VB. Generally there are only minor modifications when moving classes from Visual Basic to LotusScript.
If you don’t have Lotus Notes then just write to class in Visual Basic (6) and I will test it in LotusScript.
I have already wasted several months with a developer who kept saying “almost ready” but could never finish. He did manage to finish the C++ class using Triple DES encryption but could not complete the VB class. So you already have his C++ code as a starting point – I will send this code to the winning bidder.
This time I decided to use PC1 encryption algorithm. You can download both C++ and Visual Basic source code from [url removed, login to view]
So you already have the encryption algorithms written in native code.
Your job is in two parts.
1) Replace Triple DES in existing C++ class with PC1 algorithm.
2) Write the equivalent class in LotusScript/VB.
See the attached Word document for more information.
Must be completed by Novemeber 30th, 2007.
I will not be making any advanced payments. Payment will be made using escrow.
I have a lot more projects coming soon. I would like to work with the same people on future projects.
What I need from you
1. Indicate that you can provide classes for both VC++ and LotusScript
2. Tell me about similar projects you’ve worked on.
3. Give me your best FIXED price bid.
If you have any questions then ask me.

I can do the job. I have experience in writing optimal alghoritms and I think I am fit for the task. I hope we will colaborate in the future. Best regards...
Hi, I understood your requirement clearly(c++/native VB class). You can check my product at [login to view URL] where I have used VB code for encryption. As far as c++ I have 13 years of experience. Thanks Pras Daha Fazla
I will convert your c++ library into Visual Basic library. WIll debug it and will provide you ready to work library. Also both C++ and Visual Basic library will be compatible i.e if you encrypt with one library the oth Daha Fazla
Developing the Encryption algorithm is not a big deal. I have a solution for you. I can prepare a ActiveX component that takes the string the input and gives the encrypted string as output. Reverse action can also be d Daha Fazla
