Runtime Module pytransform¶
If you have realized that the obfuscated scripts are black box for end
users, you can do more in your own Python scripts.In these cases,
pytransform would be useful.
pytransform module is distributed with obfuscated scripts,
and must be imported before running any obfuscated scripts. It also
can be used in your python scripts.
This is raised when any pytransform api failed. The argument to the exception is a string indicating the cause of the error.
It’s not available in super mode.
Return how many days left for time limitation license.
>0: valid in these days
-1: never expired
If the obfuscated script has been expired, it will raise exception and quit directly. All the code in the obfuscated script will not run, so this function will never return 0.
Get license information of obfuscated scripts.
It returns a dict with keys:
- ISSUER: The issuer id
- EXPIRED: Expired date
- IFMAC: mac address bind to this license
- HARDDISK: serial number of harddisk bind to this license
- IPV4: ipv4 address bind to this license
- DATA: extra data stored in this licese, used by extending license type
- CODE: registration code of this license
The value None means no this key in the license.
The key ISSUER is introduced from v6.2.5. It will be trial if the license.lic is generated by trial pyarmor. For purchased pyarmor, it will be the purchased key like pyarmor-vax-NNNNNN. Note that if the license.lic is generated by pyarmor before v6.0.1, it will be None.
Exceptionif license is invalid, for example, it has been expired.
Return a string in non-super mode or bytes object in super mode, which is last argument as generating the licenses for obfucated scripts.
Exceptionif license is invalid.
Return a string in non-super mode or bytes object in super mode, which is specified by
-xas generating the licenses for obfucated scripts.
Return None if no specify
Exceptionif license is invalid.
Get hardware information by hdtype, hdtype could one of
HT_HARDDISK return the serial number of first harddisk
HT_IFMAC return mac address of first network card
HT_IPV4 return ipv4 address of first network card
HT_DOMAIN return domain name of target machine
Exceptionif something is wrong.
In Linux, name is used to get named network card or named harddisk. For example:
get_hd_info(HT_IFMAC, name="eth2") get_hd_info(HT_HARDDISK, name="/dev/vda2")
In Windows, name is used to get all network cards and harddisks. For example:
get_hd_info(HT_IFMAC, name="*") get_hd_info(HT_HARDDISK, name="*") get_hd_info(HT_HARDDISK, name="/0") # First disk get_hd_info(HT_HARDDISK, name="/1") # Second disk
Changed in v6.5.3
- Add new keyword parameter name
- Remove keyword parameter size
HT_HARDDISK, HT_IFMAC, HT_IPV4, HT_DOMAIN
Constant for hdtype when calling
A decorator function used to check each module/function/method list in the args is obfuscated.
It could check module, function or method, any other type, Class for example, doesn’t support. If the function is decoratored by builtin decorator, for example
@staticmethod, it will be taken as no obfuscation.
RuntimeErrorif anyone is not obfuscated.
import foo from pytransform import assert_armored @assert_armored(foo, foo.connect, foo.connect2) def start_server(): foo.connect('root', 'root password')
Since v6.6.2, checking module is supported, but only for super mode
Return True if all the functions/methods/modules in the args are obfuscated.
Return False if any of them is not obfuscated.
It could check module, function or method, any other type, Class for example, doesn’t support. If the function is decoratored by any builtin decorator, for example,
@staticmethod, it will taken as not obfuscated and return False.
import foo from pytransform import check_armored if not check_armored(foo, foo.connect, foo.connect2): print('My script is hacked')
New in v6.6.2 only for super mode
Copy those example code to any script, for example foo.py, obfuscate it, then run the obfuscated script.
Show left days of license
from pytransform import get_license_info, get_expired_days try: code = get_license_info()['CODE'] left_days = get_expired_days() if left_days == -1: print('This license for %s is never expired' % code) else: print('This license for %s will be expired in %d days' % (code, left_days)) except Exception as e: print(e)

Though pytransform.py is not obfuscated when running the obfuscated script, it’s also protected by PyArmor. If it’s changed, the obfuscated script will raise protection exception.
