usability business / commercial software for linux

OpenCrypts aim from the beginning has always been to develop the most flexible, customizable, powerful, secure and of course easy to use membership/user management and password protection system possible, and we think weve done just that.

Offering support for unlimited subscription/membership types, linked to unlimited members areas with the ability to integrate with all major e-commerce payment processors allows for incredible flexibility over which users see what content and at what cost.
Unlimited personalised mailing lists and in-built shopping cart style system make it an incredible marketing and community building tool too and of course, sophisticated anti-hack and password abuse detection tools prevent unwanted users from gaining access to your content.
