SEAL is an easy-to-use homomorphic encryption library, developed by researchers in the Cryptography Research group at Microsoft Research. SEAL is written in C++11, and contains .NET wrappers for the public API. It has no external dependencies.
10/13/2016: Experimental Branch
A new experimental branch has been created. This branch will get much more frequent updates than the master branch, but these updates may not have been tested as thoroughly as the code in the master branch, may introduce frequent API changes,
and may contain incomplete functionality. This first experimental commit contains some significant performance improvements over SEAL v2.1.
9/30/2016: SEAL v2.1 released
Again a new version of SEAL has been released. This is a fairly large update, which focuses mostly on performance, but also introduces some small API changes.
To accompany the release and to explain the changes in SEAL v2.1, we have released a new version of the documentation, available here.
The code-base contains examples written both in C++ and in C#. These examples are heavily commented, serving as a self-contained short introduction to using the library. In addition, the .h files both in the C++ library and in the .NET wrapper
library contain detailed comments for the public API.
To learn to use SEAL, we recommend looking at the example projects, as they contain several detailed and thoroughly commented examples demonstrating most of the basic features.
A detailed manual for using the newest version of SEAL is available
