The FAAST library is developed in C++ by L. De Feo and makes use of the NTL library. It implements the algorithms presented in  , plus other algorithms needed by the author for its research on explicit isogenies.
Version 0.2.0, released on July 11 2009, is available at http://www.lix.polytechnique.fr/Labo/Luca.De-Feo/FAAST/ . The source code is distributed under the General Public License version 2 or higher.
FAAST is a very efficient library for lattices of extensions of finite fields. Our aim is to add support for arbitrary finite fields, making it an essential building block for efficient computer algebra systems.
