sigmatch

Modern C++ 20 Signature Match / Search Library

✨ Features

• 🍃 Header-only, no dependencies, no exceptions.
• ☕ Compile-time literal signature string parsing.
• ❄️ Supports full-byte wildcards (?? or **) and semi-byte wildcards (1? or *B).
• 🚀 Supports blocking (chunking) and multi-threaded for fast search.
• 🎯 Supports searching in the current process, external processes and files.
• 🍄 Customizable reader and target allow you to search on more targets (e.g. network traffic packets).

🌠 Examples

A quick example:

using namespace sigmatch_literals;

sigmatch::this_process_target target;
sigmatch::search_result result = target.in_module("**module_name**").search("1A ?? 3C ** 5* ?F"_sig);
for (const std::byte *address : result.matches()) {
    std::cout << "matched: " << address << '\n';
}
