Signet
Your seal, pressed into an app.
Signet takes a certificate you trust and presses it into an Android APK — unpacking the app, teaching it to trust the certificate, then closing it again under your own signature.
Download
Version 0.1.0Apple hasn’t notarised this app, so on first launch macOS will say it can’t verify it. Open it from System Settings → Privacy & Security → Open Anyway. Everything runs on your own machine, and nothing phones home.
What it does
- — Take a certificate — .pem, .crt, .cer, or .der — and an .apk, and hand back a new build that trusts it.
- — Clone the app under a fresh name and package, so the rebuilt copy sits beside the original with nothing to uninstall.
- — Reach every request that travels the system network stack — HttpURLConnection, OkHttp, WebView.
- — Stay on your machine from first step to last; neither the app nor the certificate is ever uploaded.
What it won’t do
- — Bend an app that pins its own certificate, or one that carries its own trust store — as some native and Unity apps do. Where it can’t, it tells you plainly instead of failing in silence.
- — Run without a few local tools in place — apktool, the Android build-tools, and a JDK. It checks first, and names whatever is missing.
