我正在尝试使用HMAC来散列数据字符串但由于某些原因我的PHP和Python脚本结果不一致......我无法弄清楚原因。
技术上工作的是Python脚本,虽然我从PHP脚本获得结果,但返回的十六进制不正确。
更新 - 我注意到的一件事是,如果我使用单行数据,那么结果是相同的。当存在多行数据时,似乎会发生不匹配。
这里的Python演示脚本 https://repl.it/BBDH/2
结果:

$hmac = hash_hmac('sha1', $data, $key);
echo "HMAC (hex) = ".$hmac;
答案 0 :(得分:2)
Shevron是对的:行结尾是不同的。
在计算哈希值之前添加:$data = str_replace("\r\n", "\n", $data);
。
这是更正后的rept.it文件。 https://repl.it/BBDF/4
