I opened a request to phpMyAdmin in which I asked them if it was possible to implement the ed25519 authentication method to connect and I got a response informing me that this authentication system was not implemented in mysqli.
So I made the request here.

Thank you 

Test script:
-- Connect into phpMA with the ed25519 method

Expected result:
-- Login successfully 

Actual result:
The server requested authentication method unknown to the client [client_ed25519]
