汇编代码实现HMAC-SHA256算法

根据提供的引用内容，HMAC-SHA256算法需要使用密钥生成函数HKDF_SHA256和SHA256哈希函数。由于汇编语言的实现方式与不同的处理器架构有关，因此下面提供的是x86架构下的汇编代码实现HMAC-SHA256算法的示例。

section .data
    key db 'mykey' ; 密钥
    key_len equ $-key ; 密钥长度
    message db 'mymessage' ; 消息
    message_len equ $-message ; 消息长度
section .text
    global _start
