这篇文章仅作为记录.脚本是我从网上搜集来的,做一个归整.
混淆包括:类名,方法名,字段名,字符串,垃圾类代码
脚本经过我的处理,做好路径配置及混淆字符标记配置后可以直接使用.
先看混淆效果图
类名混淆效果:
方法及字段混淆效果:
字符串混淆效果:
垃圾类代码效果:
接下来是脚本代码

#项目路径,会混淆该路径下的文件
ProjectPath="/Users/项目路径/"
FileDir="/Users/存放路径"
#这个路径是混淆成功后，原文本和替换文本解密对应的文件存放路径（该路径不能在项目目录或其子目录），混淆成功后会在该路径下生成一个解密时需要的文件，根据该文件的文本内容把混淆后的内容更换为原文本内容，该文件名的组成由$(date +%Y%m%d)"_"$(date +%H%M)及日期_小时组成，每分钟会不一样。所以解密的时候需要每次更换文件路径

使用:
- 把脚本代码添加到 obfuscation.sh 和dis_obfuscation.sh 中 配置好路径,及混淆字符串(如:要混淆study字符 要写成 obf_study_fuc)
- 终端cd到脚本所在目录 执行 chmod 777 obfuscation.sh
- 执行 ./obfuscation.sh ，或直接把文件拖入到终端，回车即可
- 还原时 把生成的 tihuan20200603_1714 文件路径替换好 再执行 ./dis_obfuscation.sh
- 设置HxOrJm=2或其它值非1的值，可以按tihuan20200603_1714 文件的内容还原为原混淆代码。
字符串混淆脚本(需要python环境)
项目代码中需加入下边这些宏定义以及还原字符串方法
//confusion_NSSTRING(@"字符串混淆加密 和 解密的宏开关")
//#define obfuscation_confusion
#ifdef obfuscation_confusion
#define confusion_NSSTRING(string) obf_decryptConstString_fuc(string)
#else
#define confusion_NSSTRING(string) string
#endif
static NSString* obf_decryptConstString_fuc(NSString* s){
//confusion_NSSTRING(@"先执行decryptConfusionString函数解密字符串")
if(s.length > 0){
NSString *t = [[NSString alloc]initWithData:[[NSData alloc]initWithBase64EncodedString:s options:0] encoding:NSUTF8StringEncoding];
NSRegularExpression *r = [NSRegularExpression regularExpressionWithPattern:@"[^a-zA-Z0-9\u4e00-\u9fa5/@?%&_:.=-\\]" options:NSRegularExpressionCaseInsensitive | NSRegularExpressionUseUnixLineSeparators | NSRegularExpressionDotMatchesLineSeparators | NSRegularExpressionAnchorsMatchLines | NSRegularExpressionAllowCommentsAndWhitespace error:nil];
t = [r stringByReplacingMatchesInString:t options:0 range:NSMakeRange(0, [t length]) withTemplate:@""];
if(t.length > 0){

使用:
- 将脚本代码添加到 confusion.py 和 decrypt.py 文件中,设置好项目路径,标记要混淆的字符串明文, 如:要混淆 NSLog(@"url = %@",url) 写成NSLog(confusion_NSSTRING(@"url = %@"),url)
- 混淆明文字符串 在终端运行 python 脚本所在目录/confusion.py，或直接把文件拖入到终端，回车即可
- 还原明文字符串 在终端运行 python 脚本所在目录/decrypt.py，或直接把文件拖入到终端，回车即可

使用:
- 将代码添加到obfuscation_addCode.py文件中
- 配置好存放目录
- 终端执行 python 脚本所在目录/obfuscation_addCode.py，或直接把文件拖入到终端，回车即可
先执行这个脚本生成垃圾类代码,再执行上面的混淆脚本,可以把生成的垃圾类一起混淆
脚本文件的编辑使用的 Sublime Text
最后,混淆之前,做好备份~!
