1. Create a Linux user for the SFTP server, for example, sftpuser, which do not require a password.
2. On the SFTP server, generate the RSA public and private key pair.
3. Run the command ssh-keygen -t rsa to generate the RSA private and public key files, id_rsa and, respectively.
4. Copy the content of the public key file into the file authorized_keys, located in the user home folder, /home/sftpuser/.ssh/authorized_keys.
