CAST stub README
The code in this directory consists of stubs for the CAST-128 encryption algorithm. I have unbundled the internal CAST implementation from the SRP distribution (along with all other encryption algorithms) to make SRP easier to distribute worldwide.
If you are using OpenSSL, these stubs should interface with the OpenSSL library's CAST implementation. If you use another cryptographic library without CAST, like GNU MP or CryptoLib, and you want to use CAST, and you're in the United States or Canada, contact me at <tjw@cs.stanford.edu> and I'll send you a copy. Unpack 'cast.tar.gz' in the top-level SRP distribution directory, and it will replace the stubs in this directory with the real thing.
