The BlowFish Machine is an advanced encryption COM server. The Server permits developers to easily add file and string encryption services to web servers, internet applications and standalone desktop programs. The Server is based upon the Blowfish cryptographic algorithm and supports key sizes from 56 bits to 448 bits. This is a high speed, ultra light component that can be accessed from compiled languages and scripts that are COM-aware. The Server has high scalability and can handle thousands of concurrent encryption requests. A test program is included to permit verification of the correctness of the implementation of the Blowfish algorithm. Nine sample programs with complete source code are provided.
