2.1. Highest security and performance
The following options could improve security
--enable-rftalmost doesn’t impact performance
--enable-bccmay be a little faster than a plain script, but it consumes more memory to load binary code
--enable-jitprevents static decompilation
--enable-themidaprevents most of debuggers, only available in Windows, and reduces performance remarkably
--mix-strprotects string constants in the script
pyarmor cfg mix_argnames=1may broken annotations
2could make it more difficult to reverse byte code
The following options hide module attributes
The following options prevent functions or modules from being replaced by hack code
Using default options and the following settings
With these options, the security is almost the same as .pyc
In order to improve security, and doesn’t reduce performance, also enable RFT mode
If there are sensitive strings, enable mix-str with filter
pyarmor cfg mix.str:includes "/regular expression/"
Without the filter, all of the string constants in the scripts are encrypted, which may reduce performance. Using filter only encrypt the sensitive string may balance security and performance.
For Django application or serving web request
For most applications and packages
If RFT mode and BCC mode are available
If RFT mode and BCC mode are not available
If care about monkey trick, also
--assert-callwith inline marker to make sure all the key functions are protected
If it’s not performance sensitive, using
--enable-themidaprevent from debuggers
Move main script module level code to other module
Pyarmor will clear the module level code after the module is imported, the injected code could not get any module level code because it’s gone.
But the main script module level code is never cleared, so moving unnecessary code here to another module could improve security.
