In those days, the Vietnam War was in the spotlight, TCP / IP didn’t exist yet, Jimi Hendrix died 6 months ago, telnet was the new tough guy, and some of the most influential rock and roll artists were about to release their masterpieces, while FTP used a network protocol called NCP…
FTP has been enhanced 16 times over the years, adding support for TCP / IP, a secure extension also known as FTPS that uses the same technology as HTTPS, and more recent additions such as IPv6 support.
Fifty years after its inception, FTP is still very relevant, and millions of FTP servers are still available on the internetwhich is quite surprising given the bad news background from many people and companies like Dropbox writing about how bad FTP is combines a protocol with a complete product. Not to mention, the closest they’ve gotten to FTP is a much less flamboyant proprietary API that can only be used if Dropbox is kind enough to provide you with the key.
In 2021, what appears to be recognized progress is taking the form of proprietary protocols made behind closed doors and without any RFCs. Instead, vendors looking to build competing servers are left with reverse engineering the SDK, as did Minio with S3.
Also, how could we touch on the FTP topic without remembering the most infamous comment on HackerNews, which was the main source of inspiration for the creation of Filestash. Indeed, I believe it shouldn’t matter which protocol my mom’s tool uses. Once this tool is easy to use, she will be able to transfer the photos she wants to share, open videos, and all other things that shouldn’t require her to know about the protocol, as our engineering job is to abstract all of these tricky things so that someone who wants to access their bank account using a familiar browser does not have to choose a cipher when negotiating SSL.
