True if the algorithm is capable of signing data; false otherwise. To
test if a given key object can sign data, use CanSign and HasPrivate.</comment>

        <comment>
Some keys have private parts, some don't.  This is the class of those which do.

        <comment>
The crypographic hash functions are (being functions) unique and are,
when secure, assumed unambiguous (the whole point of being hash
functions). That is, when you have the right hash, you have the right
document. Currently (2001/9) only SHA is given that property.
