Detailed Description

This file contains helper classes/functions for implementing public key algorithms.

The class hierachies in this .h file tend to look like this:

                  x1
                 / \
                y1  z1
                 |  |
            x2<y1>  x2<z1>
                 |  |
                y2  z2
                 |  |
            x3<y2>  x3<z2>
                 |  |
                y3  z3

• x1, y1, z1 are abstract interface classes defined in cryptlib.h
• x2, y2, z2 are implementations of the interfaces using "abstract policies", which are pure virtual functions that should return interfaces to interchangeable algorithms. These classes have "Base" suffixes.
• x3, y3, z3 hold actual algorithms and implement those virtual functions. These classes have "Impl" suffixes.

The "TF_" prefix means an implementation using trapdoor functions on integers. The "DL_" prefix means an implementation using group operations (in groups where discrete log is hard).
