The Drive Trust Alliance software (sedutil) is an Open Source (GPLv3) effort to make Self Encrypting Drive technology freely available to everyone. It is a combination of the two known available Open Source code bases today: msed and OpalTool.

The DTA Open Source can be employed freely not only for higher security applications but also for integration in embedded applications such as Automotive, Aerospace, Home Automation, and everywhere where the Data Leakage problem has already become obvious and where it will be obvious. The storage device suppliers are already gearing to give you self-encrypting storage. All you have to do is work with them.
