Hash Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,

a hash table, also known as a hash table, is a data structure that is accessed directly from a key value. That is, it accesses records by mapping key code values to a location in the table to speed up lookups. This mapping function is called a hash

Previous wordsThe basic certification described in the previous article is convenient and flexible, but extremely unsafe. The user name and password are transmitted in clear text, and no action is taken to prevent tampering with the message. The

If you want to define authentication, my personal preference is that authentication is an action to determine whether the real identity of the authenticated party matches the identity of the authenticated party or her Claim (Claim. The authenticated
