Protect your Windows software from reverse engineering
AkiProtect wraps your EXE or DLL in a hardened runtime stub with code virtualization, anti-debug, anti-tamper and anti-dump — so your binary is harder to crack, patch, or steal.

What AkiProtect does for your binary
Eight protection layers, each individually configurable.
Compression
LZ77, LZ4, LZNT1 and LZMS codecs reduce binary size and reshape the on-disk image so signature scanners cannot match raw strings or constants.
Code virtualization
A custom register VM with build-randomized opcode maps. Two builds of the same binary execute different bytecode. Up to 8 independent VM passes.
Ulam block layout
Payload blocks are permuted via an Ulam-spiral order and grouped with SHA-256 integrity sets. Any tampering with the packed file breaks loading.
Anti-debug
Six runtime probes detect debuggers, breakpoints, single-step tracing and runtime hooks. Mismatch triggers silent termination — no information leaks to the attacker.
Anti-tamper
The runtime stub hashes its own .text section at startup and verifies it against a value embedded by the builder. Patching the stub breaks the binary.
Anti-dump
After mapping, the payload PE headers are wiped from the image in memory. Process dumps captured later do not yield a directly-loadable PE.
String obfuscation
Every string literal in the stealth stub is XOR-encoded at compile time and decoded into a transient buffer at use site, leaving no plaintext in the on-disk binary.
Import-less stub
WinAPI calls are resolved at runtime via PEB walking. The packed binary has no static import table — fewer static signals for analysis tools.
One-click protection — no command line required
AkiProtect ships with a Qt6 desktop application for Windows. Open your EXE, pick a preset, click Protect. The CLI is still there if you need it for CI.
Why AkiProtect
Indie developers
Ship shareware, games and utilities without handing your reverse engineers a free trial of your source code.
Game studios
Protect launchers and standalone tools alongside your anti-cheat. Frustrate trainer authors and bot writers before they ever see your logic.
B2B vendors
Keep proprietary algorithms — pricing models, optimizers, signal processing — out of competitor hands.
Compliance teams
Add a tamper-evident layer to internal tools so audit trails detect unauthorized modification.
