4. MAC有很多实现方式,比较通用的是基于hash算法的MAC,也就说HMAC是MAC的一个特例。 方法1:HMAC is a recipe forturning hash functions(such as MD5 or SHA256)into MACs.So HMAC-MD5 and HMAC-SHA256 are specific MAC algorithms, just like QuickSort is a specific sorting algorithm. 根据RFC-2104HMAC...

You can use the MacAlgorithmProvider to enumerate the available MAC algorithms and generate a symmetric key. You can use static methods on the CryptographicEngine class to perform the necessary encryption that creates the MAC value.Digital signatures are the public key equivalent of private key ...
A larger hash bucket size will lower device forwarding performance. After you change the hash bucket size to a smaller value, you need to restart the switch. Verifying the Configuration Run the display mac-address hash-mode command to check the running and configured hash algorithms.翻訳...

hashlib.algorithms_available 一个集合,其中包含在所运行的 Python 解释器上可用的哈希算法的名称。 将这些名称传给new()时将可被识别。algorithms_guaranteed将总是它的一个子集。 同样的算法在此集合中可能以不同的名称出现多次(这是 OpenSSL 的原因)。
