Reverse Engineer C++ DLL to C#

@Cumuc

Hi, I am here to start journey with you right away. I believe I’d be a great fit for your project since I handle complex reverse-engineering tasks accurately and on time. I have strong experience working with C++ DLLs and understanding low-level file operations. I’ve also converted C++ logic to C# for clients, ensuring the code works seamlessly in the new environment. You need to analyze a DLL to see how it reads and writes text files, then replicate that logic in C#. The main goal is to understand and translate the functionality correctly. This project will give you a working C# implementation based on the original C++ logic. If you want to move forward with me or have any question, let's chat. Thank you. Ghennadii

⚠ NO PAYMENT UNLESS YOU'RE SATISFIED ⚠ I’ve reverse engineered native C++ DLLs using IDA and Ghidra, traced file I/O and custom codecs, and ported core logic cleanly to C#. I can map how the function reads and writes text files, document the decoding steps, and reproduce the behavior with safe, readable C#. Static and dynamic analysis, string and control flow recovery, plus unit tests to verify byte-for-byte equivalence with your samples. Clear notes, before–after specs, and maintainable C# with async I/O where it fits. Do you have the DLL, sample input output files, and a target .NET version so I can align the port and tests correctly?

@shabahathabib

Hello, I can assist you with reverse engineering the C++ DLL to understand exactly how the function handles text file read/write operations, including any encryption, decryption, or custom encoding logic. Once the behavior is fully analyzed, I will replicate the functionality in C# with clean and well-documented code. I have strong experience in low-level C++ debugging, reverse engineering compiled binaries, and translating that logic into high-level languages like C#. This includes working with disassemblers/debuggers, analyzing memory usage, and tracing function calls to accurately capture how data is being processed. You will receive a C# implementation that mirrors the original DLL’s logic, along with clear explanations of the reverse-engineered process so you can maintain or extend the code independently. Could you share the DLL and any sample files so I can begin analyzing the structure and provide you with a detailed plan of action? Best regards, -Shabahat!

@jerryx

I am experienced in both C++ and C#. Having more than 20 years programming and debugging applications on Windows, I knew much about the internals of both languages as well as Windows API. I can provide you professional support for your project.

@TheSecondSource

Good day! I specialize in software reverse engineering and cross-language development, and I understand you need to analyze a C++ DLL and translate its file handling logic to C#. Here’s how we can help: • Reverse engineer the DLL to identify how the target function reads, writes, and possibly encodes/decodes text files • Map the logic accurately, including any decryption or data transformation processes • Convert the extracted logic into clean, functional C# code that replicates the DLL behavior • Test and verify the C# implementation to ensure it produces identical results to the original DLL Our team of 62 professionals, with over 9 years of experience in C++ and C# development, reverse engineering, and data processing, will provide a robust, maintainable solution. Do you have the DLL with symbols available, or is it a fully compiled binary? Also, are there any constraints on replicating encryption/decryption routines in C# for compliance reasons?

@stadnichuk

@rusned

Hello, I read your brief and understand that you need an experienced infrastructure developer to analyze a Windows DLL, document its behavior, and deliver usable interfaces in a clean, legal, and minimally disruptive manner to your existing development stack. My experience includes Ghidra/IDA-based rollback, PE internals, and developing secure, cleanroom SDKs in C/C# once the behavior is mapped. ✔ I will start with a legality/ownership check and scope confirmation. Then, I will identify the binary (hashes, imports/exports, TLS, relocations) and reference behavior in a controlled virtual machine. ✔ I will perform static analysis (Ghidra/IDA: call graphs, decompilation, RTTI recovery) and dynamic tracing (x64dbg/WinDbg/ProcMon) to map APIs, structures, calling conventions, and edge cases. ✔ I'll rebuild data types and protocols, write harnesses to validate outputs, and produce a clean, high-level specification and an optional C/C# wrapper so you can access the DLL's functionality securely. I'll take full responsibility for post-delivery issues: bug fixes, clarifications, and minor tweaks are my responsibility. I'm easy to work with, communicate clearly, and keep you informed with concise, plain-language notes and comparisons. If this suits your needs, I'm ready to get started after a brief nondisclosure agreement and delivery of a sample DLL. Sincerely, Ruslan

@Maxwilsonad

Hello, Hope you're doing great. I can reverse-engineer your C++ DLL (with your permission/rights) to uncover exactly how the target function reads/writes text files, then port that logic to clean, well-tested C#. My approach: static + dynamic analysis using Ghidra/IDA and x64dbg to map imports, identify the file I/O routine, and trace encoding/obfuscation (e.g., XOR/AES, custom headers, compression). I’ll document the algorithm, edge cases (line endings, UTF-8/UTF-16, BOMs), and error handling. Deliverables include: a concise report (call graph, pseudocode, formats), a C# class/library implementing the same behavior with .NET equivalents (FileStream/StreamReader/StreamWriter), and unit tests that validate against your sample files. I have 4 years of experience in Website Development, Graphic Design, Website Design, Logo Design, WordPress, HTML, CSS, PHP, Full Stack Development, Website customization, theme customization, and API integrations. Let’s connect to discuss your vision—I’d love to bring this recruitment piece to life and help attract the next generation of firefighter/paramedics. Feel free to message me to get started!
