Pyarmor is a command line tool used to obfuscate python scripts, bind obfuscated scripts to fixed machine or expire obfuscated scripts. It protects Python scripts by the following ways:
- Obfuscate code object to protect constants and literal strings.
- Obfuscate co_code of each function (code object) in runtime.
- Clear f_locals of frame as soon as code object completed execution.
- Verify the license file of obfuscated scripts while running it.

In order to improve security and support Python 3.11, there are significant changes in the next major version Pyarmor 8.0
Pyarmor 8.0 release date is about 2023-03-08 (March 8, 2023) (delay one week)
The main features for Pyarmor 8.0
- Support Python 3.11
- BCC mode for x86_64 and arm64, the enhancement of spp mode, Irreversible
- RFT mode, rename function/method/class/variable/argument, Irreversible
- Customize and localize runtime error messages
The scheduled features for Pyarmor 8.0+ (not released with 8.0)
- BCC mode for armv7 and x86
- Support Python 3.12
Pyarmor status will be stable by the end of 2024 (Dec. 31, 2024)
The big changes of EULA for Pyarmor 8.0+
- For non-profit usage, one license is OK.
- For commercial usage, one product one license.
There are only 2 new license types for Pyarmor 8.0+
- pyarmor-basic, one license price 52$
- pyarmor-pro, one license price 89$
The main differences for each type
- pyarmor-pro: 2 irreversible obfuscation modes BCC/RFT
- pyarmor-basic: no BCC/RFT modes
- pyarmor trial version: can't obfuscate big file
The old license code starts with "pyarmor-vax-" could be upgraded to pyarmor-basic without extra fee following new EULA. If it's personal license type, it need provide the product name bind to pyarmor-basic for commercial usage.
A few features may not work once Pyarmor 8.0.1 is released:
-
SPP mode doesn't work for Pyarmor prior to 8.0.1
In order to use SPP mode, it's necessary to upgrade Pyarmor to 8.0+
-
Querying registration information by "pyarmor register" (no arguments) doesn't work in future, it always return error even there is a valid license
The command "pyarmor -v" could be used to check whether the registration is successful
-
Registering Pyarmor by "pyarmor register pyarmor-vax-xxxxxx.txt" can be used no more than 10 times
If using Pyarmor in CI server or docker, regsiter Pyarmor by the second method described in the registration file "pyarmor-vax-xxxxxx.txt"
