ZuluCrypt is good for this as well.

Hi!
Can you explain why you wouldn't want to use https://mega.nz/?
Their service (chats, messaging, data sharing) is E2E-encrypted, you get 50GB free (!) storage space, and their interface is superbly translated if you need something else than English and it is very well designed. Keybase on the other hand is a design catastrophy.
You don't need a binary, you just use it by going online with the browser of your choice and login.

I can highly recommend MEGA! (No, I'm not being paid by them!)

      SOLUSfiddler Hey! The main reason that I don't want to use MEGA is because it doesn't have a native app that I can use on Solus. Using web apps are inherently less secure than using native apps as explained in this blog post by the ProtonMail team: https://protonmail.com/blog/cryptographic-architecture-response/ (Check Claim 1). Secondly, I heard that the 50 GB they give is only valid for a period of 6 months and it defaults to a maximum free storage of 15 GB after that period is over. It also ranked low on Cloudward's list for best cloud storage services on Linux: https://www.cloudwards.net/cloud-storage-for-linux/. I checked several reviews and none of them particularly favoured MEGA. I also got the hint from several reviews that MEGA is kind of shady. I am not sure but I can't verify it. Hence, I don't use it. I hope this explains it to you. Thanks for asking, man! 😃

      elfprince It doesn't sound simple to me, bro! 😂 Why don't you use the archive manager to just create an encrypted version of the folder as described in this article: https://www.addictivetips.com/ubuntu-linux-tips/encrypt-files-on-linux/? Isn't it simpler? 🤔

      Harvey I checked it out. Thanks for the suggestion, dude! It does seem like a lot of work, though. I don't want to partition my local drive into volumes, either. Could you explain to me how this allows me to keep my stuff on a cloud storage service secure? I am not extremely tech savvy and it is not very clear to me. I will appreciate it if you can explain it to me. 😄

              One of those new Raspberry Pi 4s would make a great Nextcloud server.

              It's not really as difficult as it sounds. It creates a single file that is a mountable file system its no more complicated then having a usb drive with your private information stored on it. Only this file system exists virtually an thus not requiring a device. It creates a file that acts as if it is a hard drive. You can put that file anywhere you wish, dropbox, google drive, an ftp server etc its entirely useless unless you have the password and / or keyfile to access its contents.

              I only quickly browsed this video but it seems to resemble what I have done myself only using windows instead of creating it on linux.

                  dlalinsp I realize that it is no point keeping/storing an encrypted file/folder solely on your working hard drive, because when (not if) the drive fails, that data will be lost. So, I keep encrypted copies of my precious data in the cloud as well. Any encryption method of your choice may be used, and then transfer the data to the cloud/external storage device of your choice. :-)

                      dlalinsp There is an UI, Keybase is in Solus Software Center. For the File system there is no need for more UI. It is integrated in you Filesystem of your PC/OS. In this particular example, your Solus. Just hinting, if you missunderstood something maybe.

                          nodq Oh! My bad! While I appreciate this suggestion, is not KeyBase a tool better designed for collaborative work? After researching it a bit more, I found that it supports chatting and several other functions which I don't require. I just need something simple to backup some stuff and very occasionally share a few things. Although I understand why you would recommend it (it being open source, having end-to-end encryption and providing 250 GB for free), I feel it is too bloated for my use case. If you know of any similar but simpler alternatives, please feel free to suggest them on this thread. Thanks, man! 👍️

                          Harvey Thanks for taking the time to educate me, dude! I learnt a lot. 😃

                          elfprince Thanks for the advice, dude! Thanks to you and everyone else on this forum, I am going to use pCloud. While Tresorit does seem to have more security, pCloud is perfect for those who are security conscious but are on a budget and use Linux. It also has slightly better support for Linux than Tresorit (due to providing AppImages instead of shell scripts). Its only problem is that I have to pay separately in order to get end-to-end encryption. While I do plan on getting that, I can get by for now with the advice that you guys have given me. By encrypting my own data manually, I also have more control over my data. Hence, pCloud wins over Tresorit by a small margin. Thanks again, everyone! 😄 😃 😎

                                UPDATE: I am currently using Cryptomator to encrypt my files on pCloud. I recommend it to anyone who wants to secure his/her files in the cloud. https://cryptomator.org/ 👍️

                                Hi there!
                                Thanks for your detailed reply, doesn't happen that often!
                                I am a MEGA user since April 2017 and still have those 50 GB storage I was initially given - for free.
                                Maybe they changed that in the meantime but I don't know.

                                So, there are perfectly good reasons for using MEGA and for not using their service.

                                I'm on the "use it!" side of things.

                                    Looks like it is still alpha. "So as one of our first testers: back up anything you put into Keybase's alpha, and remember: we can't recover lost encrypted data."

                                    I'm late to this thread but found it interesting. I'm all in w/ PCloud. They have a nice 'crypto' vault for some more sensitive documents and I love that you can pay one time for lifetime access. I enjoy Cozy.io - open source and you can host your own server - but waiting for an encrypted option. In the meantime I pay the min to support the cause.

                                    I've long given up on dropbox or google.

                                    I have 4tb lifetime on pcloud. The appimage runs great. I can use the built in media player to access my songs and videos from any device. I'm actually using it with Solus and Kodi now to host my home media server.
