Detailed Description

template<class uint_type, unsigned blockSizeInBytes>
class SHADigest< uint_type, blockSizeInBytes >

SHADigest Base class for the SHA*Digests.

Generic Class that is the base class of the various SHA*Digest classes.

uint_type == The "Unsigned Integer Type" which is large enough to hold the total length of a given message in bits. For SHA1 and SHA256, this is 64 bits, so we use "uint64";

"blockSizeInBytes" == various SHA digests use different message size blocks - the basic units in which to split a message up in. For example, SHA1 and SHA256 use 512 bit blocks, and so in bytes this is 64.
