如何运用codesign达到授权签名目的

最编程 2024-02-17 14:02:39
...

codesign就是创建和管理证书的。下面列举一些基本的操作使用。

可以查看codesign的使用帮助

codesign --help

使用方法的命令

Usage: codesign -s identity [-fv*] [-o flags] [-r reqs] [-i ident] path ... # sign
       codesign -v [-v*] [-R=<req string>|-R <req file path>] path|[+]pid ... # verify
       codesign -d [options] path ... # display contents
       codesign -h pid ... # display hosting paths

查看签名

比如我们看一下xcode的签名,我们使用 -d -v 参数,-d 是display展示签名信息的意思,-v 是verbose的意思,越多的verbose显示信息越多,通常3个就已经足够了。

codesign -d -vvv WeChat.app 
Executable=/Users/ruicong/Desktop/com.tencent.xin-iOS9.0-(Clutch-2.0.4)/Payload/WeChat.app/WeChat
Identifier=com.tencent.xin
Format=app bundle with Mach-O thin (arm64)
CodeDirectory v=20500 size=1951259 flags=0x0(none) hashes=30483+7 location=embedded
Hash type=sha256 size=32
CandidateCDHash sha1=8b199f83297c9d4dfce84acdd247a3d07c2438b5

上面的签名中没有显示一些额外的信息,比如授权机制 entitements信息 。那么如何显示证书中的其他信息呢,在查看时使用 --entitlements 选项可以查看,比如:

codesign -d --entitlements - WeChat.app 
Executable=/Users/ruicong/Desktop/com.tencent.xin-iOS9.0-(Clutch-2.0.4)/Payload/WeChat.app/WeChat
??qqm<?xml version="1.0" encoding="UTF-8"?>

</plist>%                                                  

签名

签名使用codesign -s 命令,s就是签名sign的意思

签名需要一个证书,我们可以打开 钥匙串应用 查看我们拥有的证书,或者通过命令行使用security命令访问钥匙串,查找可以签名的证书,

security find-identity -v -p codesigning
 1) 63CDF0F7E792C6037B5D695F55181ABF09E652DD "iPhone Developer: jmhmobile@jchtcorp.com (FRSJUDZYE3)"

为了方便起见,我就创建一个my.app文件。创建文件可以使用 touch 命令

来到桌面
cd ~/Desktop 
touch my.app

查看是否签名

codesign -d -vvv my.app 
my.app: code object is not signed at all

然后签名的时候,指定此证书进行签名就可以了

 codesign -s "iPhone Developer: 812883574@qq.com (8QLSY8DC93)" my.app 

然后可以使用上的命令查看签名状态

codesign -d -vvv my.app 
Executable=/Users/ruicong/Desktop/my.app
Identifier=my
Format=generic
CodeDirectory v=20200 size=130 flags=0x0(none) hashes=0+2 location=embedded

如果想要重新签名 那么需要加上-f参数,-f的意思是force的意思,如果没有这个参数,签名不会不替换,签名操作会失败。

修改签名参数

  • 修改Identifier
    需要使用-i参数
codesign -f -i com.123.ok -s "iPhone Developer: 812883574@qq.com (8QLSY8DC93)" my.app

my.app: replacing existing signature

新的查看命令

codesign -d --verbose=4 my.app 

修改后的效果

  • 修改flags
    使用参数-o
codesign -f -o 0x2200 -s "iPhone Developer: 812883574@qq.com (8QLSY8DC93)" my.app 
my.app: replacing existing signature

  • 重新签名framwork
    1.先cd到framwork目录下
cd Frameworks 

2.然后查看有多少个库要签名,最后一个一个进行重签名

ls

OpenSSL.framework       andromeda.framework     marsbridgenetwork.framework
ProtobufLite.framework      mars.framework          matrixreport.framework

codesign -fs "iPhone Developer: 812883574@qq.com (8QLSY8DC93)" OpenSSL.framework

给不是可执行文件,

上可执行文件权限
先cd到WeChat.app目录下

chmod +x WeChat

查看描述文件

security cms -Di embedded.mobileprovision

对app包进行签名

1.先得在xcode中创建一个plist文件,然后把描述文件中的授权文件拷到这个plist文件中,然后把这个plist文件拷贝到和WeChat.app一起
这里的 no-strict 是不严谨的,--entitlements=en.plist权限文件来自哪个文件

codesign -fs "iPhone Developer: 812883574@qq.com (8QLSY8DC93)" --no-strict --entitlements=en.plist WeChat.app
