# zsign
Maybe is the most quickly codesign alternative for iOS12+ in the world, cross-platform ( Linux & macOS ), more features.  
If this tool can help you, please don't forget to star me. :) 

### Compile

You must install openssl library at first.

#### macOS:

```bash
brew install openssl
```
and then (attention to replace your openssl version)
```bash
g++ *.cpp common/*.cpp -lcrypto -I/usr/local/Cellar/openssl/1.0.2s/include -L/usr/local/Cellar/openssl/1.0.2s/lib -O3 -o zsign
```

#### Windows/MingW:
Note:  These instructions describe how to cross-compile for Windows from
Linux.  I haven't tested these steps compiling for Windows from Windows,
but it should mostly work.

These instructions assume that mman-win32, zsign, and openssl are all
sibling directories

1.  Install MingW
```bash
apt-get install mingw-w64

```
2. Build mman-win32

```bash
git clone git@github.com:witwall/mman-win32
cd mman-win32
./configure ----cross-prefix=x86_64-w64-mingw32-
make
```

3.  Build openssl
```
git clone github.com:openssl/openssl
cd openssl
git checkout OpenSSL_1_0_2s
./Configure --cross-compile-prefix=x86_64-w64-mingw32 mingw64
make

```

4. Build zsign
```bash
x86_64-w64-mingw32-g++  \
*.cpp common/*.cpp -o zsign.exe 
-lcrypto -I../mman-win32 
-std=c++11  -I../openssl/include/  
-DWINDOWS -L../openssl 
-L../mman-win32 
-lmman -lgdi32  
-m64 -static -static-libgcc
```

#### CentOS7:


```bash
yum install openssl-devel
```
and then
```bash
g++ *.cpp common/*.cpp -lcrypto -O3 -o zsign
```

### Usage
I have already tested on macOS and Linux, but you also need **unzip** and **zip** command installed.

```bash
Usage: zsign [-options] [-k privkey.pem] [-m dev.prov] [-o output.ipa] file|folder

options:
-k, --pkey          Path to private key or p12 file. (PEM or DER format)
-m, --prov          Path to mobile provisioning profile.
-c, --cert          Path to certificate file. (PEM or DER format)
-d, --debug         Generate debug output files. (.zsign_debug folder)
-f, --force         Force sign without cache when signing folder.
-o, --output        Path to output ipa file.
-p, --password      Password for private key or p12 file.
-b, --bundleid      New bundle id to change.
-n, --bundlename    New bundle name to change.
-e, --entitlements  New entitlements to change.
-z, --ziplevel      Compressed level when output the ipa file. (0-9)
-l, --dylib         Path to inject dylib file.
-w, --weak          Inject dylib as LC_LOAD_WEAK_DYLIB.
-i, --install       Install ipa file using ideviceinstaller command for test.
-q, --quiet         Quiet operation.
-v, --version       Show version.
-h, --help          Show help.
```

1. Show mach-o and codesignature segment info.
```bash
./zsign demo.app/execute
```

2. Sign ipa with private key and mobileprovisioning file.
```bash
./zsign -k privkey.pem -m dev.prov -o output.ipa -z 9 demo.ipa
```

3. Sign folder with p12 and mobileprovisioning file (using cache).
```bash
./zsign -k dev.p12 -p 123 -m dev.prov -o output.ipa demo.app
```

4. Sign folder with p12 and mobileprovisioning file (without cache).
```bash
./zsign -f -k dev.p12 -p 123 -m dev.prov -o output.ipa demo.app
```

5. Inject dylib into ipa and re-sign.
```bash
./zsign -k dev.p12 -p 123 -m dev.prov -o output.ipa -l demo.dylib demo.ipa 
```

6. Change bundle id and bundle name
```bash
./zsign -k dev.p12 -p 123 -m dev.prov -o output.ipa -b 'com.tree.new.bee' -n 'TreeNewBee' demo.ipa
```

7. Inject dylib(LC_LOAD_DYLIB) into mach-o file.
```bash
./zsign -l "@executable_path/demo.dylib" demo.app/execute
```

8. Inject dylib(LC_LOAD_WEAK_DYLIB) into mach-o file.
```bash
./zsign -w -l "@executable_path/demo.dylib" demo.app/execute
```

### Use xmake to compile

If you have [xmake](https://xmake.io) installed, you can use xmake to quickly compile and run it.

#### Build

```console
xmake
```

#### Run

```console
xmake run zsign [-options] [-k privkey.pem] [-m dev.prov] [-o output.ipa] file|folder
```

#### Install

```console
xmake install
```

#### Get zsign binary

```console
xmake install -o outputdir
```

binary: `outputdir/bin/zsign`

### Docker
1. Build:
```
docker build -t zsign https://github.com/zhlynn/zsign.git
```

2. Run:

*Mount current directory (stored in $PWD) to container and set WORKDIR to it:*
```
docker run -v "$PWD:$PWD" -w "$PWD" zsign -k privkey.pem -m dev.prov -o output.ipa -z 9 demo.ipa
```

*If input files are outside current folder, you will need to mount different folder:*
```
docker run -v "/source/input:/target/input" -w "/target/input" zsign -k privkey.pem -m dev.prov -o output.ipa -z 9 demo.ipa
```

### Copyright
zsign is completely free. Please mark the source of zsign in your commercial product if possible.

### How to sign quickly?
You can unzip the ipa file at first, and then using zsign to sign folder with assets.  
At the first time of sign, zsign will perform the complete signing and cache the signed info into *.zsign_cache* dir at the current path.  
When you re-sign the folder with other assets next time, zsign will use the cache to accelerate the operation. Extremely fast! You can have a try！：）
