Man Page¶
PyArmor is a command line tool used to obfuscate python scripts, bind obfuscated scripts to fixed machine or expire obfuscated scripts.
The syntax of the pyarmor
command is:
pyarmor <command> [options]
The most commonly used pyarmor commands are:
obfuscate Obfuscate python scripts
licenses Generate new licenses for obfuscated scripts
pack Pack obfuscated scripts to one bundle
hdinfo Show hardware information
The commands for project:
init Create a project to manage obfuscated scripts
config Update project settings
build Obfuscate all the scripts in the project
info Show project information
check Check consistency of project
The other commands:
benchmark Run benchmark test in current machine
register Make registration file work
download Download platform-dependent dynamic libraries
runtime Generate runtime package separately
See pyarmor <command> -h for more information on a specific command.
Note
From v5.7.1, the first character is command alias for most usage commands:
obfuscate, licenses, pack, init, config, build
For example:
pyarmor o => pyarmor obfuscate

DESCRIPTION
PyArmor first checks whether Global Capsule exists in the HOME
path. If not, make it.
Then find all the scripts to be obfuscated. There are 3 modes to search the scripts:
- Normal: find all the .py files in the same path of entry script
- Recursive: find all the .py files in the path of entry script recursively
- Exact: only these scripts list in the command line
Note that only the .py files are touched by this command, all the other files aren’t copied to output path. If there are many data files in the package, first copy the whole package to the output path, then obfuscate the .py files, thus all the .py files in the output path are overwritten by the obfuscated ones.
If there is an entry script, PyArmor will modify it, insert cross protection code into the entry script.
Next obfuscate all these scripts in the default output path dist.
After that make the Runtime Package in the dist path.
Finally insert the Bootstrap Code into entry script.
If --exact
is set, all the scripts in the command line are taken as entry
scripts. Otherwise only the first script is entry script.
Option --src
used to specify source path if entry script is not in the top
most path. For example:
# if no option --src, the "./mysite" is the source path
pyarmor obfuscate --src "." --recursive mysite/wsgi.py
Option --plugin
is used to extend license type of obfuscated scripts, it
will inject the content of plugin into the obfuscated scripts. The corresponding
filename of plugin is NAME.py. Name may be absolute path if it’s not in the
current path, or specify plugin path by environment variable PYARMOR_PLUGIN.
More information about plugin, refer to How to Deal With Plugins, and here is a real example to show usage of plugin Using Plugin to Extend License Type
Option --platform
is used to specify the target platform of obfuscated
scripts if target platform is different from build platform. Use this option
multiple times if the obfuscated scripts are being to run many platforms. From
v5.7.5, the platform names are standardized, command download could list all
the available platform names.
Option --restrict
is used to set restrict mode, Restrict Mode
RUNTIME FILES
By default the runtime files will be saved in the separated folder pytransform
as package:
pytransform/
__init__.py
_pytransform.so, or _pytransform.dll in Windows, _pytransform.dylib in MacOS
pytransform.key
license.lic
But if --package-runtime
is 0, they will be saved in the same path with
obfuscated scripts as four separated files:
pytransform.py
_pytransform.so, or _pytransform.dll in Windows, _pytransform.dylib in MacOS
pytransform.key
license.lic
If the option --enable-suffix
is set, the runtime package or module name
will be pytransform_xxx
, here xxx
is unique suffix based on the
registration code of PyArmor.
BOOTSTRAP CODE
By default, the following Bootstrap Code will be inserted into the entry script:
from pytransform import pyarmor_runtime
pyarmor_runtime()
If the entry script is __init__.py
, the Bootstrap Code will make a
relative import by using leading dots like this:
from .pytransform import pyarmor_runtime
pyarmor_runtime()
But the option --bootstrap
is set to 2
, the Bootstrap Code always
makes absolute import without leading dots. If it is set to 3
, the
Bootstrap Code always makes relative import with leading dots.
If the option --enable-suffix
is set, the bootstrap code may like this:
from pytransform_vax_000001 import pyarmor_runtime
pyarmor_runtime(suffix='vax_000001')
If --no-bootstrap
is set, or --bootstrap
is 0, then no bootstrap code
will be inserted into the entry scripts.
EXAMPLES
Obfuscate all the .py only in the current path:
pyarmor obfuscate foo.py
Obfuscate all the .py in the current path recursively:
pyarmor obfuscate --recursive foo.py
Obfuscate all the .py in the current path recursively, but entry script not in top most path:
pyarmor obfuscate --src "." --recursive mysite/wsgi.py
Obfuscate a script foo.py only, no runtime files:
pyarmor obfuscate --no-runtime --exact foo.py
Obfuscate all the .py in a path recursive, no entry script, no generate runtime package:
pyarmor obfuscate --recursive --no-runtime . pyarmor obfuscate --recursive --no-runtime src/
Obfuscate all the .py in the current path recursively, exclude all the .py in the path build and tests:
pyarmor obfuscate --recursive --exclude build,tests foo.py pyarmor obfuscate --recursive --exclude build --exclude tests foo.py
Obfuscate only two scripts foo.py, moda.py exactly:
pyarmor obfuscate --exact foo.py moda.py
Obfuscate all the .py file in the path mypkg/:
pyarmor obfuscate --output dist/mypkg mypkg/__init__.py
Obfuscate all the .py files in the current path, but do not insert cross protection code into obfuscated script
dist/foo.py
:pyarmor obfuscate --no-cross-protection foo.py
Obfuscate all the .py files in the current path, but do not insert bootstrap code at the beginning of obfuscated script
dist/foo.py
:pyarmor obfuscate --no-bootstrap foo.py
Insert the content of
check_ntp_time.py
into foo.py, then obfuscating foo.py:pyarmor obfuscate --plugin check_ntp_time foo.py
Only plugin assert_armored is called then inject it into the foo.py:
pyarmor obfuscate --plugin @assert_armored foo.py
Obfuscate the scripts in Macos and run obfuscated scripts in Ubuntu:
pyarmor obfuscate --platform linux.x86_64 foo.py
Obfuscate the scripts in advanced mode:
pyarmor obfuscate --advanced 1 foo.py
Obfuscate the scripts with restrict mode 2:
pyarmor obfuscate --restrict 2 foo.py
Obfuscate all the .py files in the current path except __init__.py with restrice mode 4:
pyarmor obfuscate --restrict 4 --exclude __init__.py --recursive .
Obfuscate a package with unique runtime package name:
cd /path/to/mypkg pyarmor obfuscate -r --enable-suffix --output dist/mypkg __init__.py
licenses¶
Generate new licenses for obfuscated scripts.
SYNOPSIS:
pyarmor licenses <options> CODE
OPTIONS
-O, --output OUTPUT | |
Output path, stdout is supported | |
-e, --expired YYYY-MM-DD | |
Expired date for this license | |
-d, --bind-disk SN | |
Bind license to serial number of harddisk | |
-4, --bind-ipv4 IPV4 | |
Bind license to ipv4 addr | |
-m, --bind-mac MACADDR | |
Bind license to mac addr | |
-x, --bind-data DATA | |
Pass extra data to license, used to extend license type | |
--disable-restrict-mode | |
Disable all the restrict modes | |
--enable-period-mode | |
Check license per hour when the obfuscated script is running |
DESCRIPTION
In order to run obfuscated scripts, it’s necessarey to hava a license.lic. As obfuscating the scripts, there is a default license.lic created at the same time. In this license the obfuscated scripts can run on any machine and never expired.
This command is used to generate new licenses for obfuscated scripts. For example:
pyarmor licenses --expired 2019-10-10 mycode
An expired license will be generated in the default output path plus code name licenses/mycode, then overwrite the old one in the same path of obfuscated script:
cp licenses/mycode/license.lic dist/pytransform/
Another example, bind obfuscated scripts in mac address and expired on 2019-10-10:
pyarmor licenses --expired 2019-10-10 --bind-mac 2a:33:50:46:8f tom
cp licenses/tom/license.lic dist/pytransform/
Before this, run command hdinfo to get hardware information:
pyarmor hdinfo
By option -x any data could be saved into the license file, it’s mainly used to extend license tyoe. For example:
pyarmor licenses -x "2019-02-15" tom
In the obfuscated scripts, the data passed by -x could be got by this way:
from pytransfrom import get_license_info
info = get_license_info()
print(info['DATA'])
It also could output the license key in the stdout other than a file:
pyarmor --silent licenses --output stdout -x "2019-05-20" reg-0001
Note
Here is a real example Using Plugin to Extend License Type
pack¶
Obfuscate the scripts and pack them into one bundle.
SYNOPSIS:
pyarmor pack <options> SCRIPT | PROJECT
OPTIONS
-O, --output PATH | |
Directory to put final built distributions in. | |
-e, --options OPTIONS | |
Pass these extra options to pyinstaller | |
-x, --xoptions OPTIONS | |
Pass these extra options to pyarmor obfuscate | |
-s FILE | Use external .spec file to pack the scripts |
--without-license | |
Do not generate license for obfuscated scripts | |
--with-license FILE | |
Use this license file other than default one | |
--clean | Remove cached files before packing |
--debug | Do not remove build files after packing |
--name | Name to assign to the bundled (default: the script’s basename) |
DESCRIPTION
The command pack first calls PyInstaller to generate .spec file which
name is same as entry script. The options specified by --options
will be
pass to PyInstaller to generate .spec file. It could any option accepted by
PyInstaller except --distpath
.
If there is in trouble, make sure this .spec works with PyInstaller. For example:
pyinstaller myscript.spec
Then pack will obfuscates all the .py files in the same path of entry
script. It will call pyarmor obfuscate with options -r
, --output
, and
the extra options specified by --xoptions
.
Next pack patches the .spec file so that the original scripts could be replaced with the obfuscated ones.
Finally pack call PyInstaller with this pacthed .spec file to generate the final distributions.
For more information, refer to How To Pack Obfuscated Scripts.
Note
Since v5.9.0, possible pack one project directly by specify the project path in the command line. For example, create a project in the current path, then pack it:
pyarmor init --entry main.py
pyarmor pack .
By this way the obfuscated scripts could be fully controlled.
Important
The command pack will obfuscate the scripts automatically, do not try to pack the obfuscated the scripts.
EXAMPLES
Obfuscate foo.py and pack them into the bundle dist/foo:
pyarmor pack foo.py
Remove the build folder, and start a clean pack:
pyarmor pack --clean foo.py
Pack the obfuscated scripts by an exists myfoo.spec:
pyarmor pack -s myfoo.spec foo.py
Pass extra options to run PyInstaller:
pyarmor pack -e " -w --icon app.ico" foo.py
Pass extra options to obfuscate scripts:
pyarmor pack -x " --exclude venv --exclude test" foo.py
Pack the obfuscated script to one file and in advanced mode:
pyarmor pack -e " --onefile" -x " --advanced" foo.py
Pack the obfuscated scripts and expired on 2020-12-25:
pyarmor licenses -e 2020-12-25 cy2020 pyarmor pack --with-license licenses/cy2020/license.lic foo.py
Change the final bundle name to my_app other than foo:
pyarmor pack --name my_app foo.py
Pack a project with advanced mode:
pyarmor init --entry main.py pyarmor config --advanced 1 pyarmor pack .
hdinfo¶
Show hardware information of this machine, such as serial number of hard disk, mac address of network card etc. The information got here could be as input data to generate license file for obfuscated scripts.
SYNOPSIS:
pyarmor hdinfo
If pyarmor isn’t installed, downlad this tool hdinfo
And run it directly:
hdinfo
It will print the same hardware information as pyarmor hdinfo
init¶
Create a project to manage obfuscated scripts.

This command will create a project in the specify PATH, and a file .pyarmor_config will be created at the same time, which is project configuration of JSON format.
If the option --type
is set to auto, which is the default value, the
project type will set to pkg if the entry script is __init__.py, otherwise
to app.

This command mainly used to download available dynamic libraries for cross platform.
List all available standard platform names. For examples:
pyarmor download
pyarmor download --help-platform
pyarmor download --help-platform windows
pyarmor download --help-platform linux.x86_64
Then download one from the list. For example:
pyarmor download linux.armv7
pyarmor download linux.x86_64
By default the download file will be saved in the path ~/.pyarmor/platforms
with different platform names.
Option --list
could filter the platform by name, arch, features, and display
the information in details. For examples:
pyarmor download --list
pyarmor download --list windows
pyarmor download --list windows.x86_64
pyarmor download --list JIT
pyarmor download --list armv7
After pyarmor is upgraded, however these downloaded dynamic libraries won’t be
upgraded. The option --update
could be used to update all these downloaded
files. For example:
pyarmor download --update
runtime¶
Geneate Runtime Package separately.
SYNOPSIS:
pyarmor runtime <options>
OPTIONS:
-O, --output PATH | |
Output path, default is dist | |
-n, --no-package | |
Generate runtime files without package | |
-i, --inside | Generate bootstrap script which is used inside one package |
-L, --with-license FILE | |
Replace default license with this file | |
--platform NAME | |
Generate runtime package for specified platform | |
--enable-suffix | |
Generate the runtime package with unique name |
DESCRIPTION
This command is used to generate the runtime package separately.
The runtiem package could be shared if the scripts are obufscated by same Global Capsule. So generate it once, then need not generate the runtime files when obfuscating the scripts later.
It also generates a bootstrap script pytransform_bootstrap.py
in the output
path. This script is obfuscated from an empty script, and there is
Bootstrap Code in it. It’s mainly used to run Bootstrap Code in
the plain script. For example, once it’s imported, all the other obfuscated
modules could be imported in one plain script:
import pytransform_bootstrap
import obf_foo
If option --inside
is specified, it will generate bootstrap package
pytransform_bootstrap
other than one single script.
About option --platform
and --enable-suffix
, refer to command
obfuscate
EXAMPLES
Generate Runtime Package
pytransform
in the default path dist:pyarmor runtime
Not generate a package, but four separate files Runtime Files:
pyarmor runtime -n
Generate bootstrap package
dist/pytransform_boostrap
:pyarmor runtime -i
Generate Runtime Package for platform armv7 with expired license:
pyarmor licenses --expired 2020-01-01 code-001 pyarmor runtime --with-license licenses/code-001/license.lic --platform linux.armv7
