delphi7写的一个验证btcdice网站结果的程序

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

mark 下：

主要实现的功能有：

  Sha256算法 / hmac_sha512算法 (上网搜索了2天才搞定，资料太少)
 包含Listview 相关用法

1. Main window

2. 运行结果

ChangeLog : 2016/7/4 1:11:37   v1.3.8
1. flatlistview 倒叙排列
2. 关闭 serverseed , serverSeedHash, clientSeed 设置为只读
3. 限制 betID , betRange 只能输入数字
4. 计算 按钮默认 disable, serverseed验证成功方可开启
5. 计算开始前 需要检测betID , betRange 大小关系
