The most mature, well-debugged, and featureful Python obfuscator and code size reducer available Developed and updated 2003-2014. Benefits Impedes reverse engineering of your Python code. Useful against even bytecode disassemblers and decompilers. Can reduce code size in both source code and compiled forms. 'Industrial-strength' automation can obfuscate even large-scale programs and libraries consisting of many modules, without limitations on import syntax. A body of code containing multiple packages and subpackages can even be obfuscated as a coordinated unit, within which even the interfaces between the packages and subpackages are obfuscated. Key technical features Automated analysis and obfuscation of identifiers defined by your code: variable names, function names, function attributes, function and method argument names, class names, class and object methods, class and object variables, object names, module names, including inter-module interfaces and some inter-package interfaces. Namespace analyzer optionally avoids a 1:1 mapping of cleartext names to obfuscated names. (The same variable name or function parameter name may be converted to several different names within a piece of obfuscated code, without changing code functionality nor increasing the number of code instructions.) You can choose the format of replacement identifier names. Choose to shrink code more with smaller identifiers. Choose extra-confusing formats. Choose to have different identifier names for each customer's build (a code watermarking feature.) You may mark some names and docstrings for retention (mostly so you can produce libraries for other programmers to use.) Removes/replaces docstrings and comments. Psychologically inspired techniques produce extra confusion in human readers. Outputs Python source code for maximum flexibility. Python source code can easily be byte-compiled or converted to other formats. Copyright information can be inserted automatically. Various additional advanced options. Code to be obfuscated may include all Python 2.3, 2.4, and 2.5 language & library features. almost all language & library features added in Python 2.6 and/or 2.7. Obfuscator can be run in Python 2.5, 2.6, and 2.7 Obfuscated output code can be run in Python 2.3, 2.4, 2.5, 2.6, and 2.7 (if the code you fed into the obfuscator could run in those versions of Python.) 'Convenience features' such as Utility to deobfuscate your software's error data (aka tracebacks / stack crawls / stack dumps.) Cross-platform: operates under Windows, OS X (Macintosh), Unix/Linux. Manual for obfuscator version 3.0 Pricing: A one-user, one-machine license costs USD $200. (Permits use by one user at a time, on one machine at a time. Includes free upgrades to any later minor (.x) versions.) Please contact us for more details and to purchase an obfuscator license.
