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。
以下示例哈希一些数据和标记该哈希。 在第二个阶段中,将验证哈希及其签名。 哈希使用用户的私钥进行签名,并导出签名者的公钥,以便可以验证签名。 此示例演示了以下任务和CryptoAPI函数: 使用cryptAcquireContext获取 CSP。 使用CryptGetUserKey获取用户的AT_SIGNATURE密钥对。

We use assertions heavily to catch bad argument values. The CZMQ classes do not attempt to validate arguments and report errors; bad arguments are treated as fatal application programming errors. We also use assertions heavily on calls to system functions that are never supposed to fail, where fa...
