在现代信息安全领域,消息认证码(Message Authentication Code,简称MAC)起着至关重要的作用。Hash-based Message Authentication Code(基于哈希的MAC,简称HMAC)作为一种广泛应用的MAC算法,其性能和安全性得到了业界的认可。本文将从算法原理、优缺点、替代方案等方面,全面介绍和解释HMAC算法。 HMAC在线加密 | 一个覆盖广泛...
1、HMAC 概念 HMAC(Hash-based Message Authentication Code)基于 hash 的消息验证码,是 安全通信中必要的组成部件。 主要是 防止消息被篡改,和对称加密一起保护数据通信的 完整性。 参考HMAC实现规范,基于的 Hash 算法可以是 md5,sha1,sha-2(sha256,sha385,sha512)等; 在不考虑 hash算法具体实现的情况下,其...

How a Hash-Based Message Authentication Code Works The general formula for HMAC is: HMAC = hashFunc(secret key + message) Let’s unpack each of the elements in this formula—the secret key and the hash function—both of which serve to protect the integrity and authenticity of the message....
Hash-based message authentication code (or HMAC) is a cryptographic authentication technique that uses a hash function and a secret key. With HMAC, you can achieve authentication and verify that data is correct and authentic with shared secrets, as opposed to approaches that use signatures and asy...
