    Description

      MySQL 8.0 introduced a new authentication plugin "caching_sha2_password" plugin, which is enabled by default and will be used as standard plugin:

      Workflow:

      1) Server sends scramble packet
      2) Clients generates a sha256 hashed authentication string with the following mechanism:

        digest1= sha256(password)
      		 
        digest2= sha256(digest1)
      		 
        digest3= sha256(digest2, scramble)
      		 
        digest4= xor(digest1, digest3)

      3) Client sends digest4 as authentication string

      On success server sends a packet with length=1 and content=3. In case the password was not cached, server requires same authentication mechanism as in sha256_password with a little difference, the padding algorithm is PKCS1 v1.5 padding instead of OAEP.
