hmac_sha256:C C ++中最少的HMAC-SHA256实现-源码

hmac_sha256 在C / C ++中最小化HMAC-SHA256实现 该存储库提供了最少的HMAC-Sha256代码，您可以将其复制到自己的项目中。 hmac_sha256函数如下所示： size_t // Returns the number of bytes written to `out` hmac_sha256 ( // [in]: The key and its length. // Should be at least 32 bytes long for optimal security. const void * key, const size_t keylen, // [in]: The data to hash alongside the key. const void * data, const size_t
