# Introduction In the year 2150, humanity has embarked on a bold journey across the stars, exploring new worlds with the help of advanced technology. Our scenario begins on the outskirts of the Alpha Centauri system, where a space exploration engineer is tasked with setting up a communications hub on a newly established base. The goal is clear: to securely transfer critical mission files from Earth's control center to the hub's secure server, ensuring that all the information relating to the colonization efforts, technological blueprints, and scientific data is transmitted without compromise. Only a robust and secure method will suffice in the vast expanse of space, where the slightest error can have monumental consequences. The engineer must utilize the skill of secure file transferring via _sftp_, an encrypted network protocol that provides file access, transfer, and management capabilities. As the engineer, your role is to master this protocol to protect the integrity and privacy of the exploratory mission's data. Your task is to ensure that all communication between Earth and the Alpha Centauri outpost is safeguarded against any potential intrusions or eavesdropping by nefarious forces lurking among the stars.
