hmac_ctx_init 函数通常与 OpenSSL 库中的 HMAC 相关功能相关联。但在 OpenSSL 的标准文档中,并没有直接提及 hmac_ctx_init 函数。可能存在的是 HMAC_CTX_init,这是一个在 OpenSSL 1.1.0 之前用于初始化 HMAC 上下文的函数。 检查项目是否已正确包含并链接了该库: 确保你的项目中已经包含了 OpenSSL 的头文...

ctx must have been created with HMAC_CTX_new() before the first use of an HMAC_CTX in this function. If HMAC_Init_ex() is called with key NULL and evp_md is not the same as the previous digest used by ctx then an error is returned because reuse of an existing key with a ...

问错误:聚合“HMAC_CTX ctx”类型不完整,无法定义EN对于小白而言,运行编写的程序遇到报错,往往不知所措,不清楚什么原因造成的。完美的程序是不存在的,程序有异常才是常态,所以遇到缺陷不要慌,找到错误根因解决它就行了。 本节就专门介绍一下编程过程可能遇到的一些错误,如果你能识别这些异常原因并fix,那么...
