C++ Signature Scanner

Original C++ implementation of the Signature Scanner library.

Building

Open SignatureScanner.sln in Visual Studio and build the project.

Recent Improvements (2024)

The C++ implementation has been modernized with significant improvements:

Platform Compatibility

• 64-bit Support: All pointer and address types updated from unsigned long to uintptr_t for proper 32/64-bit compatibility
• Memory Size Handling: Uses SIZE_T for memory operations to prevent truncation on 64-bit systems
• Cross-Platform Types: Eliminates platform-specific size assumptions

Security & Safety

• Buffer Safety: Replaced unsafe sprintf with sprintf_s to prevent buffer overflows
• Proper Bounds Checking: Added buffer size validation in string formatting operations
• Memory Protection: Fixed VirtualProtect parameter handling to prevent NULL pointer issues

Code Quality

• Type Safety: Eliminated implicit type conversions that could cause data loss
• Modern C++ Types: Uses size_t for string lengths and loop counters
• Compiler Warnings: Resolved all MSVC compilation warnings and errors
• Logic Fixes: Corrected logical vs bitwise operator usage

API Improvements

• Return Types: Functions now return uintptr_t instead of unsigned long for addresses
• Vector Support: Uses standard vector<uintptr_t> instead of custom typedef
• Parameter Types: Updated function parameters for consistency and safety

These improvements ensure the library compiles cleanly on modern Visual Studio versions and provides better reliability across different system architectures.

Usage

#include "SignatureScanner.h"

// Initialize
signature_scanner* sig = new signature_scanner();

// Search for pattern with wildcards
uintptr_t address = sig->search("3AB2DFAB????????3FBACD300200A1XXXXXXXXB1C4DA");

// Search for text
uintptr_t address = sig->search_text("Hello World");

// Find all matches
vector<uintptr_t> results;
bool found = sig->find_all(results, "pattern");
