Cryptography background

This chapter of the manual provides an overview of the various cryptographic schemes implemented by this package. It is recommended that all users go through this entire chapter. Even those familiar with the cryptographic schemes in question, will find this chapter of value as a gentle usage introduction for the underyling mathematical primitives, as well as hopefully a straightforward statement of the actual cryptographic protocol and notational conventions used in this package (since they sometimes differ between different papers in the literature.)
