基於Xposed的通用破解簽名的方法

@Override
public void initZygote(IXposedHookZygoteInit.StartupParam startupParam) throws Throwable {
    XposedBridge.log("initZygote: " + startupParam.toString());
    XposedHelpers.findAndHookMethod("java.security.Signature", null, "verify", byte[].class, new XC_MethodHook() {
        protected void afterHookedMethod(MethodHookParam param) throws Throwable {
            XposedBridge.log("Signature verify disabled");
            param.setResult(Boolean.TRUE);
        }
    });
}

啓用xposed插件後，任意修改APK包的文件，無須重新簽名就可以安裝成功。
