Encryption/Decryption classes - VB, C++

Introduction

============

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.

Background

==========

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

========

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.

Deadline

========

Must be completed by Novemeber 30th, 2007.

Payments

========

I will not be making any advanced payments. Payment will be made using escrow.

Future Work

=========

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.

Employer questions: (1) Do you understand that there are two classes required - one class in C++ and one class in Visual Basic/LotusScript?

(2) Can you meet the deadline of Novemeber 30th?

Taidot: C-ohjelmointi, Linux, PHP, Visual Basic, Windows Desktop
