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:

brew install openssl

and then (attention to replace your openssl version)

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

CentOS7:

yum install openssl-devel

and then

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.

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)

-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.

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！：）
