key编程注意事项

//-----------------------------------//get public keyif(CryptGetUserKey( m_hCSPProv, AT_SIGNATURE, &hKey)) {printf("The signature key has been acquired. /n");}else{//这里不能调用GenKey, 要不导致重新生成公私钥对，把Key给毁了。//由于Key的故障,导致公钥读取失败, 直接返回FALSE才是正确的.//如果Key有问题，初始化Key和重新生成公私钥对的工作是CA才有权利做的.//GenKey操作把原有的公私钥对给毁了, 如果联系CA不方便，那很麻烦/*if(!CryptGenKey(m_hCSPProv,AT_SIGNATURE,0,&hKey))HandleError("Error during CryptGetUserKey for signkey.");*/return S_FALSE;}
