Dear Sir or Madam,

I’m reaching out as Open-source Advocate for PrestaShop which is the
designer and editor of an open source software solution, released under a
free license (Open Software Licence OSL-3.0), allowing its users to create
e-commerce websites in a quick and simplified way.

 -  Secure the accounting data,

In order to satisfy a potential inspection of the tax administration.

In addition to these properties, the law requires that merchants use a

INFOCERT’requests, the code source of the module has been obfuscated.

Before releasing the module, we would like to know your stands on the

Indeed, as the PrestaShop solution is open-source, we are concerned about
the compatibility of the OSL licence and the code-source obfuscation of the

I thank you in advance and remain at your disposal if you have any
additional questions or concerns.

Best Regards,

Antoine THOMAS
