Hello,
when I use the ECDH<ECP>::Domain class as a member property of a class an
call the contructor in the of ECDH<ECP>::Domain in the following way:
class TestClass {
public:
// construction and destruction
TestClass() : mecdh(CryptoPP::ASN1::secp224r1()) {
} // TestClass()
~TestClass() {
} // TestClass()
public:
CryptoPP::ECDH<ECP>::Domain mecdh;
}; // TestClass()
TestClass tc;
Then there are occuring a application crash, when the object is defined. In
my case the object is defined globally in the application, so it crashs
immediately.
Im using MSVC/C++ 7.0 on WXP! With Crypto++ version < 5.0 and using the
successor of ECDH<ECP>::Domain ==>> ECDHC<ECP> this has worked.
Any hints or workarounds?
Alex
