Public key authentication is a way of logging into an SSH/SFTP account using a cryptographic key rather than a password. Configuring an SSH user for public key authentication requires both a public SSH key and a private SSH key (also known as an SSH key pair). Any compromise of the private key will allow the attacker to log into servers that are configured with the associated public key without additional authentication. 秘密キー ファイルはパスワードと同等であり、すべての状況下で保護される必要があります。 You need both keys for authentication.
