I'm looking for client-side encryption software for Windows 10, that can be used for any cloud storage service (Dropbox, OneDrive, Google Drive etc.). I used to use BoxCryptor Classic, but that doesn't work for Windows 10. The current BoxCryptor version can't be bought, only rented, and I while I don't mind paying a reasonable one-time price, I don't want a keep-paying-forever-solution.
I've looked at, and excluded, these programs so far:
- BoxCryptor Classic - Perfect match for my use case on Windows 7 & 8, but doesn't work on Windows 10.
- BoxCryptor - Can't be bought, only rented.
- Cloudfogger - Got killed just a few days ago.
- Cryptomator - At present, this doesn't work for my use case due to a couple of bugs. Exe files in CryptoMator vaults sometimes won't start or even copy. Some programs can't read files from vaults, e.g. OpenVPN can't read config files. IMHO, the fundamental design is great and Cryptomator could be the best alternative if and when the bugs are fixed.
- EncFS4win - A revival of the discontinued encfs4win. Randomly unmounts encrypted drives while copying large directory structures. File name encryption creates long names, resulting in file paths that are too long for Windows.
- PanBox - According to creators, Windows 10 support is experimental at present (July 2016). I ran into problems showing that it's not ready for use. Some examples: "Error 0x800705AA: Insufficient system resources exist to complete the requested service" when copying large directories, attempts to copy files are ignored if there's already a file with the same name present (no overwrite/rename dialog, the operation is just ignored), sometimes files are shown in the explorer view but when you try to open or delete them you get an error that the file doesn't exist. Update 2019-05-12: PanBox is gone.
- Safe - Doesn't work on Windows 10: attempting to create a safe either results in error message "Unexpected Error Occurred" or Safe simply hangs during the creation process. Only one contributor on GitHub. Seems abandoned since 2014.
- VeraCrypt - Great for what it's built for: encryption of local storage. Not for the cloud, unless you enjoy uploading a 5 GB virtual drive image to Dropbox every time you change a 5 kB text file.
- Viivo - Uses one encrypted folder (for cloud sync) and a synchronized plain text folder. That means that everything you sync to the cloud takes twice the disk space (I'm trying a synced plain text folder now. Syncing has been stuck at 28228 files of 33000 totaling 2.7GB for 3 hours now). You can use it without the synchronized plain text folder, but then you can't open your files from within your programs. You can only double click them to have them opened by their default programs. That's plain weird.
I know about git-annex, but starting to use it seems a project in itself, including studying new, arcane concepts and getting 3 different projects (git-annex, rcloud, GnuPG) working together. I might spend a weekend or two on it as a last resort, but primarily I'm looking for something you just install and run, i.e. like Cryptomator but without the bugs.
