Cryptomator VS android

the best way to do this is with https://cryptomator.org

Before putting anything on a cloud service I would recommend 3rd party tools, like Cryptomator, to encrypt folders and such, then upload to a cloud service.

I use Cryptomator - https://cryptomator.org

I've used countless encryption "schemes" over the years, from True/Vera-Crypt to encrypted sparse bundles/images, and none have ever really felt right.

These days i tend to use Cryptomator[0] instead. It accomplishes what none of the others could do, which is transparent encryption across devices.

With Cryptomator, i simply create a vault somewhere in the cloud, stuff data in it, and i can access it from my laptop, phone or tablet, and not think much about it. It integrates into the normal file browsing APIs, and doesn't get in the way.

Because it does "per file" encryption, it also doesn't need to download a 20-100MB chunk from the cloud before decrypting, so it's rather fast (depending on file size of course).

Cryptomator's arguably the most popular encryption software for cloud storage (you can give yourself zero-knowledge encryption by using them) - it's actually what they specialize & focus on (cloud encryption). It's 100% open source and Free to use on computers. On phones I believe it's just a 1-time fee of a few bucks ($13-14, then you have it forever) - note: their iOS offering is still new, so may be a bit unpolished at the moment.

Cryptomator. It is made for uploading files securely to cloud storage, but works locally, is easy to use, and completely free for your use case.

When you only want to access the files you could wait for the freemium cryptomator app for android: https://github.com/cryptomator/android/issues/428

You can install cryptomator by adding the following url in obtainium:https://github.com/cryptomator/android/releases/

Such apps exist. Essentially they require a license key before accesing. For example, Cryptomator (github) and Threema (github) .

Cryptomator (version 2772): Put a lock on your cloud: Take the security of your data into your own hands

Ah, I see what you're asking. They don't have any free trial features, especially for the Android app. You can try to compile the apk yourself though. I don't believe you need the license key if you compile the code. https://github.com/cryptomator/android

It sounds like you are mixing some terms up. Open Source Software does not mean free of charge. The source code is open, modifiable (and usually instructions are given to build it). However, there are some licenses for this software. Cryptomator's Android code is here: https://github.com/cryptomator/android and the license, what to do with this software is here (You obviously can't just stick a different logo on top and sell it as your product).

You mean this? https://github.com/cryptomator/android

Its tracked in Github

Yep, also want to point out the app is actually open source, the only reason it's paid on Google Play is so that you can support the devs: https://github.com/cryptomator/android
