HashInfo Structure

Allows application to determine characteristics of the digest algorithm.

struct HashInfo {
char name[32];/**< null terminated ascii string e.g. "SHA-1" */
unsigned int blockLength;/**< optimal hash block size */
unsigned int hashLength;/**< size of hash value */
struct HashObj * hobj; /**< version 1 */
};
typedef struct HashInfo HashInfo;
