Detailed Description

template<class T>
class DL_Algorithm_GDSA_ISO15946< T >

German Digital Signature Algorithm.

Template Parameters
TFieldElement type or class The Digital Signature Scheme ECGDSA does not define the algorithm over integers. Rather, the signature algorithm is only defined over elliptic curves. However, The library design is such that the generic algorithm reside in gfpcrypt.h.
