Nancy -- The answer is yes, a C encryption module can easily (trivially?) be integrated with a GT.M implementation of VistA. But there's encryption and there's encryption. Do you want public/private key (usually used to exchange keys for symmetric encryption rather than as the actual encryption key)? Do you want symmetric encryption? Do you want a cryptographic hash rather than encryption? So, the more interesting question is what you want or need. Once the encryption code is all set up, the actual interfacing to GT.M is a matter of a few minutes.
