PKard Toolkit

The royalty free PKard® Toolkit is commercial US software that supports both Apple and Android secure app development for in-house and Independent Software Vendors (ISVs).  New apps participate in a secure app ecosystem that includes well over twenty thousand early adopters -- the largest production group in the market.


We have a developer and demo kit available for partners who do not have a PKI infrastructure in place. Also, while most of our developers are able to integrate with our toolkit in a matter of days, this kit includes engineering support for those developers that are tackling more complex integration schemes.

Our history in strong security

Thursby has been delivering enterprise integration, management and security for over a quarter century, with strong security at the world’s largest user of PKI, secure web and email, the DoD, over the past decade.  Thursby were invited by Apple to harden Mac OS X for use by the US Army worldwide in 2006, extending CAC and PIV support across the US Government for GFE (government furnished equipment) workstations and laptops, as well as home users and their personal devices .   The same technology was brought to the iPad, iPhone and iOS in 2011, now live for tens of thousands of productions users, and Android in 2014, reflecting the growth in secure enterprise usage of those new mobile platforms.

Adding new smart card types

  • For a new smart card type, 95% of the stack is already in place
  • The 5% additional functionality can be added either by integrating a licensed and pre-existing card library, or custom building, where permitted, from sample cards and specifications
