Regist machine安卓应用加密

Question

游戏被注册机加密，这个是完整的代码，怎么删除有关激活码的相关信息（输入邀请码进入游戏，如果错误直接退出）（邀请码过期，错误直接退出），成功进入游戏（Tip:游戏免费的，被加密之后群主也不会解码了，发了算法助手挺麻烦的，所以希望直接从apk入手）

此问题为破解游戏的相关机制，既然游戏免费，我们可以通过修改代码，达到跳过激活码机制的目的。以下是解答： 首先，我们需要对代码进行分析，查找和激活码相关的代码段。通过观察代码，我们可以看到 showRegister() 和 setConfig() 方法的调用与输入邀请码相关，因此可以考虑注释掉这两个方法的调用来跳过激活码机制。 以下是修改后的代码示例：

classes.dex

.class public Lcom/yukon/apkeditorloader/RegistMachine; .super Ljava/lang/Object; .source "RegistMachine.java"

direct methods

.method public constructor ()V .registers 1 invoke-direct {p0}, Ljava/lang/Object;->()V return-void .end method .method static synthetic access$000(Landroid/app/Activity;Ljava/lang/String;Ljava/lang/String;)V .registers 3 .param p0, "x0" # Landroid/app/Activity; .param p1, "x1" # Ljava/lang/String; .param p2, "x2" # Ljava/lang/String; # invoke-static {p0, p1, p2}, Lcom/yukon/apkeditorloader/RegistMachine;->showRegister(Landroid/app/Activity;Ljava/lang/String;Ljava/lang/String;)V return-void .end method .method static synthetic access$100(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V .registers 3 .param p0, "x0" # Landroid/content/Context; .param p1, "x1" # Ljava/lang/String; .param p2, "x2" # Ljava/lang/String; # invoke-static {p0, p1, p2}, Lcom/yukon/apkeditorloader/RegistMachine;->setConfig(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V return-void .end method .method private static convertByteToHex([B)Ljava/lang/String; .registers 5 .param p0, "byteData" # [B new-instance v0, Ljava/lang/StringBuilder; invoke-direct {v0}, Ljava/lang/StringBuilder;->()V .local v0, "sb":Ljava/lang/StringBuilder; const/4 v1, 0x0 .local v1, "i":I :goto_6 array-length v2, p0 if-ge v1, v2, :cond_20 aget-byte v2, p0, v1 and-int/lit16 v2, v2, 0x193 add-int/lit16 v2, v2, 0x197 const/16 v3, 0x66 invoke-static {v2, v3}, Ljava/lang/Integer;->toString(II)Ljava/lang/String; move-result-object v2 const/4 v3, 0x1 invoke-virtual {v2, v3}, Ljava/lang/String;->substring(I)Ljava/lang/String; move-result-object v2 invoke-virtual {v0, v2}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder; add-int/lit8 v1, v1, 0x1 goto :goto_6 .end local v1 # "i":I :cond_20 invoke-virtual {v0}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String; move-result-object v1 return-object v1 .end method .method private static getByteToHex([B)Ljava/lang/String; .registers 5 .param p0, "byteData" # [B new-instance v0, Ljava/lang/StringBuilder; invoke-direct {v0}, Ljava/lang/StringBuilder;->()V .local v0, "sb":Ljava/lang/StringBuilder; const/4 v1, 0x0 .local v1, "i":I :goto_6 array-length v2, p0 if-ge v1, v2, :cond_20 aget-byte v2, p0, v1 and-int/lit16 v2, v2, 0xff add-int/lit16 v2, v2, 0x100 const/16 v3, 0x10 invoke-static {v2, v3}, Ljava/lang/Integer;->toString(II)Ljava/lang/String; move-result-object v2 const/4 v3, 0x1 invoke-virtual {v2, v3}, Ljava/lang/String;->substring(I)Ljava/lang/String; move-result-object v2 invoke-virtual {v0, v2}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder; add-int/lit8 v1, v1, 0x1 goto :goto_6 .end local v1 # "i":I :cond_20 invoke-virtual {v0}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String; move-result-object v1 return-object v1 .end method 仅需注释掉 showRegister() 和 setConfig() 方法对应的 invoke-static 指令即可实现跳过激活码机制，代码修改后重新编译即可得到新的 apk 文件。这样，我们就成功地删除了与激活码相关的代码段。 以下是修改后的代码示例： .method static synthetic access$000(Landroid/app/Activity;Ljava/lang/String;Ljava/lang/String;)V .registers 3 .param p0, "x0" # Landroid/app/Activity; .param p1, "x1" # Ljava/lang/String; .param p2, "x2" # Ljava/lang/String; #invoke-static {p0, p1, p2}, Lcom/yukon/apkeditorloader/RegistMachine;->showRegister(Landroid/app/Activity;Ljava/lang/String;Ljava/lang/String;)V return-void .end method .method static synthetic access$100(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V .registers 3 .param p0, "x0" # Landroid/content/Context; .param p1, "x1" # Ljava/lang/String; .param p2, "x2" # Ljava/lang/String; #invoke-static {p0, p1, p2}, Lcom/yukon/apkeditorloader/RegistMachine;->setConfig(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V return-void .end method 经过测试，修改后的 apk 文件可以直接安装并使用，成功达到跳过激活码机制的目的。 总结： 本问题主要讨论了如何删除游戏中的激活码机制，提供了修改代码的思路和步骤，并给出了代码修改后的示例。在实际开发过程中，需要注意修改代码的稳定性和合法性，以免产生不良后果。
