How it works
The resign process is performed on a Mac machine within the Customer's environs.
The Keychain on the signing Mac should include:
- The enterprise certificate used to resign the instrumented application,
- Mobileprovision file matching the enterprise certificate.
Perfecto will provide the user with a script, to run on the Mac machine, that executes the following steps (see diagram above):
step 1: Upload the application file (*.ipa file) to Perfecto's instrumentation service.
step 2: Download the instrumented application file (*.ipa file) from Perfecto's instrumentation service.
step 3: Resign the instrumented application file with the customer's certificate.
Requirements for the Mac machine
OS - High Sierra or later
XCode 8.3.3 or later
Python 3.6 and above - with "requests" module installed.
To install "requests" module run the following command:
Open to internet connection (to access Perfecto services)
Keychain on Mac should contain the required enterprise certificate (no duplicate names- verify only a single entry with this name in the keychain list)
Mobileprovision file matching the enterprise certificate
*.ipa file of the application (which should be instrumented)
Download the Python Script
Run Perfecto's resign script on the Mac machine
Run the script with the Python service.
Script name: customInstrumentWrapper.py
- Required Parameters:
-i (IPA) - Original ipa File to Instrument
-o (OUTPUT_FILE) - Name for the Instrumented ipa File
-p PROVISIONING_PROFILE - Mobile Provisioning Profile File to use
-c CERTIFICATE_NAME - Name of the Certificate to use, as saved in the Keychain
-t TOKEN - Text file Containing a Valid Security Token
-u URL - Perfecto Lab URL
-v VERSION - Perfecto Lab Version
Instrumentation Flags, at least one of the following is required:
-ih - Enables Hybrid Instrumentation
-is - Enables Sensors Instrumentation
-ent – (Optional) Entitlements File. Add a prepared entitlements plist profile in place of the generic entitlements section generated by the script, based on the information provided.
During execution - the script reports its progress through the steps indicated above.
Upon completion, the fully instrumented and signed ipa file is generated.
Limitations and troubleshooting
- Using multiple certificates to sign the application is not supported.
