Invalid license file when the license is generated on a x86_64 machine and uploaded to arm based machine
So I have a system that supports x86_64 and ARM. I obfuscated my script using an outer license. I generated a license file on my x86_64 machine and uploaded it to my ARM-based machine, but I got an error Check license failed, Invalid input packet.
Does the generation of a license, platform specific?
Thank you.
The generated license is platform independent. Make sure the same pyarmor version and same PyArmor License is used in both of 2 platforms.
Yes I have same pyarmor on x86-64 and arm64 hardware, but when i generate an outer license on my x86-64 machine and copy the generated outer license to my arm64 machine it fails, says Invalid License, invalid packet.
That's all the log, after using the license generated from my laptop It's a hassle when you support two different architectures you need to login on both architectures to generate each licenses.
Make sure arm64 scripts are obfuscated by feature 3. I said checking the log means the output log of pyarmor command. It will show which feature dll is used and more other informations. About the feature of each platform, please refer to the online document in chapter support platforms
Here is the logs:

This is the log when I generate the license on arm64
INFO PyArmor Version 7.5.1 INFO Python 3.6.9 INFO Generate licenses with capsule /root/.pyarmor/.pyarmor_capsule.zip ... INFO Output path of licenses: /home/licenses/ INFO The license file is generated in restrict mode INFO The license file is generated in period mode disabled INFO Generate license: CODE:TESTACTIVE;;;0;;; INFO Write license file: /home/licenses/TESTACTIVE/license.lic INFO Write information to /home/licenses/TESTACTIVE/license.lic.txt INFO Generate 1 licenses OK.
This is the log when I generate the license on amd64
INFO PyArmor Version 7.5.1 INFO Python 3.6.9 INFO Generate licenses for ... INFO Output path of licenses: /home/licenses/ INFO The license file is generated in restrict mode INFO The license file is generated in period mode disabled INFO Generate license: CODE:TESTACTIVE;;;0;;; INFO Write license file: /home/licenses/TESTACTIVE/license.lic INFO Write information to /home/licenses/TESTACTIVE/license.lic.txt INFO Generate 1 licenses OK.
The difference is on amd64 the line says "Generate licenses for ..." not "Generate licenses with capsule /root/.pyarmor/.pyarmor_capsule.zip ..."
Use option -d, for example, pyarmor -d licenses r001
The key is that feature 0 isn't compatible with other features not zero.

Specifying --platform linux.aarch64 solved my problem even on native linux.aarch64 machine
