Ticket 49726 - DS only accepts RSA and Fortezza cipher families
    
    Bug Description:  Currently DS only accepts fortezza and RSA cipher families.
                      This prevents things like ECC certificates from being used.
    
    Fix Description:  Instead of hardcoding the cipher families, just grab the
                      current type and use it.
    
                      Also cleaned up code: removed unncessary "ifdefs", and switched
                      for loops to use size_t.
