Detect It Easy - Web

Detect It Easy compiled to WebAssembly, running entirely in the browser.

English | 中文

Features

• Pure Frontend: No server required, runs entirely in browser
• 100% Signature Coverage: All 800+ DIE signatures included
• Multiple Formats: PE, ELF, Mach-O, MSDOS, COM, ZIP, APK, JAR, DEX, Java Class, PDF, PNG, JPEG, etc.
• Multiple Output Formats: Text, JSON, XML
• Detailed Analysis: File hashes (MD5, SHA256), entropy calculation
• Offline: Works without network connection

Demo

Upload any file to detect:

• File format with detailed info (e.g., PNG[512x512, 8 bits, RGBA])
• Compiler/Linker identification (Visual C++, GCC, Rust, Go, etc.)
• Packer/Protector detection (UPX, ASPack, MPRESS, etc.)
• Library/Framework detection (.NET, MFC, Unity, etc.)

Usage

1. Start HTTP server (WASM requires HTTP protocol):

cd docs
python3 -m http.server 8080

2. Open http://localhost:8080

3. Upload or drag-drop a file

Note: WASM cannot load from file:// protocol. Must use HTTP server.

Build WASM

Prerequisites

1. Emscripten 4.0.7 (matches Qt 6.11.1):

git clone https://github.com/emscripten-core/emsdk.git ~/emsdk
cd ~/emsdk
./emsdk install 4.0.7
./emsdk activate 4.0.7
source ~/emsdk/emsdk_env.sh

2. Qt 6.11.1 WASM:

pip install aqtinstall
aqt install-qt all_os wasm 6.11.1 wasm_singlethread -O ~/Qt
aqt install-qt linux desktop 6.11.1 linux_gcc_64 -O ~/Qt

Build

cd wasm-build
source ~/emsdk/emsdk_env.sh

# Clone DIE-engine with submodules
git clone --recursive https://github.com/horsicq/DIE-engine.git deps/DIE-engine

# Build
cd deps/DIE-engine
mkdir build-wasm && cd build-wasm
cmake .. \
    -DCMAKE_PREFIX_PATH=$HOME/Qt/6.11.1/wasm_singlethread/lib/cmake/Qt6 \
    --toolchain $HOME/Qt/6.11.1/wasm_singlethread/lib/cmake/Qt6/qt.toolchain.cmake \
    -DQT_HOST_PATH=$HOME/Qt/6.11.1/gcc_64 \
    -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_CXX_FLAGS="-Dregister=''"
emmake make -j4 diec

# Copy output
cp release/diec.* ../../docs/wasm/

Output Format

Text (default, similar to diec -p)

PNG
    Format: PNG[48x48, 8 bits, RGBA, bKGD: rgb=(255,255,255)]

JSON

{"format":{"format":"PNG","fullName":"Portable Network Graphics"...}}

XML

<?xml version="1.0" encoding="UTF-8"?>
<detect><format><name>PNG</name>...</format></detect>

Signature Coverage

Format	Signatures
PE	781

Total	800+

Technical Details

• WASM Size: ~14MB total (engine + Qt + signatures)
• Qt WASM: Uses Qt 6.11.1 for QJSEngine (signature execution)
• Emscripten: Version 4.0.7 (ABI compatible with Qt)
• FS: Virtual filesystem for file handling
