HMAC 的 OpenSSL 速度命令答案

【问题标题】：OpenSSL speed command for HMACHMAC 的 OpenSSL 速度命令
【发布时间】：2019-11-05 20:33:14
【问题描述】：

OpenSSL 提供了一个convenient command 用于基准算法。

据我了解，它只允许对加密和哈希函数进行基准测试。是否也可以从命令行对 HMAC 进行基准测试（例如 hmac-sha256）？

【解决方案1】：

发布一个更新的答案，因为我自己只是在看这个！

从 OpenSSL 3.0.0 开始，the speed utility 已更新为包含 -hmac 选项，因此您可以使用选择的摘要对 hmac 进行基准测试：

% openssl speed -hmac sha256

hmac(md5) 与 md5 的结果非常相似。

所以我想对 hmac(sha256) 进行基准测试你只需要获取 sha256 哈希函数的结果。
