dex解密

healer、

各位大神，请问这种类型的dex文件要怎么解密啊，用np管理器和mt管理器都显示不支持此种类型的解密，这个是其中一段代码：

.class public Lezy/assist/compat/SettingsCompat;
.super Ljava/lang/Object;
.source "SettingsCompat.java"

# static fields

.field private static final OP_SYSTEM_ALERT_WINDOW:I = 0x18

.field private static final OP_WRITE_SETTINGS:I = 0x17

.field private static final TAG:Ljava/lang/String; = "ezy-settings-compat"

贴il一般是没用的
dex加密是指对原dex做了一层上层封装，或者直接修改控制流了做混淆
所以贴出来的很可能是封装的壳代码或者混淆代码
这个要具体情况具体分析
一般来说有些是通用的，可以用通用工具做分析
如果上vmp之类的话只能靠人读和写代码分析
如果是运行时解密可以考虑尝试dump下来
