以下示例实现签名数据过程中所述的过程。 有关常规信息,请参阅简化的消息。 有关函数和结构的详细信息,请参阅基本加密函数、简化的消息函数,以及CryptoAPI 结构。 此示例还包括用于验证已创建的消息签名的代码。 此代码通常位于单独的程序中,但为了完整和清楚起见,此处包含此代码。
以下示例合并了对消息的签名和编码,并解码已签名的消息并验证签名。 这两个作通常位于单独的程序中。 编码示例将创建编码的消息,将其保存到磁盘文件,或者以某种其他方式将其发送到其他用户。 解码示例将收到编码的消息,对其进行解码,并验证签名。 此处已合并这两个过程,以显示这两个过程正常工作。

A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As we can see in the image uploaded above, a string is to be entered first up.

First, <string> no longer includes <iterator>. Second, <tuple> now declares std::array without including all of <array>, which can break code through the following combination of code constructs: your code has a variable named "array", and you have a using-directive "using namespace std;...
