~/.ssh/id_ed25519
~/.ssh/id_ed25519_sk
~/.ssh/id_rsa
Contains the DSA, ECDSA, authenticator-hosted ECDSA,
Ed25519, authenticator-hosted Ed25519 or RSA authentication
identity of the user. This file should not be readable by
anyone but the user. It is possible to specify a
passphrase when generating the key; that passphrase will be
used to encrypt the private part of this file using 128-bit
AES. This file is not automatically accessed by ssh-keygen
but it is offered as the default file for the private key.
ssh(1) will read this file when a login attempt is made.
~/.ssh/id_dsa.pub
~/.ssh/id_ecdsa.pub
~/.ssh/id_ecdsa_sk.pub

~/.ssh/id_rsa.pub
Contains the DSA, ECDSA, authenticator-hosted ECDSA,

wishes to log in using public key authentication. There is
no need to keep the contents of this file secret.
