IOS通过备份，得到的目录里面是一片乱码（严格来说是sha1编码）。解析出具体的文件列表的分析有很多了，整理了一下，写出来。
大概介绍下，这个文件的开头是“mbdb”，前六个字节一般是固定的“mbdb\05\00”，然后就是一个个结构体。结构体大概是这样子的：
struct fileinfo{
char *domain;
char *filename;
char *linktarget;
char *datahash;
char *unknown1;
unsigned short mode;
unsigned int unknown2;
unsigned int inode;
unsigned int userid;
unsigned int groupid;
unsigned int mtime;
unsigned int atime;
unsigned int ctime;
unsigned long long filelen;
unsigned int flag;
unsigned int numprops;
};domain就是包名，每个应用都不同。filename就是path。datahash发现现在都是空的了，无用。最后就是那个numprops是附加数据，这个必须处理。flag为0是文件夹或者link，也可以通过filelen来判断是否为文件。
备份目录里面的文件名 = sha1(domain+filename)。
直接贴个代码（引用自p0sixspwn的越狱工具中的代码，改为windows下的代码，VS可直接编译）：

用法：
将mbdb.cpp、mbdb_record.cpp、mbdb.h添加到工程中，包含.h。
mbdb_t * pList = mbdb_open((unsigned char *)"Manifest.mbdb");
//遍历
for (int i = 0; i < pList->num_records; i++)
{
printf("%s - %s\n", pList->records[i]->domain, pList->records[i]->path);
}
mbdb_free(pList);
