HMAC 计算——示例

In Python we can calculate HMAC codes as follows (using the hashlib and hmac libraries):

在 Python 中，我们可以如下计算 HMAC码（使用 hashlib 和 hmac 库）：

import hashlib, hmac, binascii

def hmac_sha256(key, msg):
  return hmac.new(key, msg, hashlib.sha256).digest()

key = b"12345"
msg = b"sample message"
print(binascii.hexlify(hmac_sha256(key, msg)))

Run the above code example: https://repl.it/@nakov/HMAC-SHA256-Examples.

可在此链接中运行该示例代码：https://repl.it/@nakov/HMAC-SHA256-Examples。

The above code will calculate and print the expected HMAC code (like in our previous example):

上面的代码将计算并打印预期的 HMAC 代码（如我们之前的示例中所示）：

Try the code yourself and play with it.

你可以尝试以上代码并修改试试。
