CryptSync (from the guy that did BowPad)

synopsis wrote:Synchronizes multiple folders with each other, keeping them up-to-date. One folder of each pair is kept encrypted.

Very useful when using cloud storage tools like SkyDrive, GDrive or Dropbox.

Has some command-line options are available that can include the password to make the process more seamless and potentially much more secure if you use a long password and can restrict physical access to your machine.

Setup process:

1. Download installer
2. Uniextract
3. Run CryptSync.exe

Verdict: Not portable (writes to registry) in HKCU\Software\CryptSync

Interesting concept though another middleman in the sync process.

I was about to create a launcher for that but interestingly if you export its registry key and import it back again, passwords are lost.
Tried with the built-in regedit.exe and other tools but no success.

Here is a thread on the portable version (feature request):

Oh excellent. Thanks for that.

Funnily enough, I was also working on a yaP launcher for it...

Old thread update: an interesting related article with a breakdown on some possible encryption tools that might help with cloud services. I'm a little skeptical with their inclusion of TrueCrypt unless you have a bit-for-bit updater (uploading the entire file each and every time is nuts).

it doesn't work on Mac.

Yeah anything that really worked with cloud services would definitely need to be cross-platform. I'll try to put together a feature request or something along those lines including a Mac component.

I checked back on this and it doesn't look like (despite a few comments promoting a portable version) the author has much interest in that. Bummer.

Edit: the portable version thread was moved here. There still doesn't appear to be any interest on the part of the developer.

CryptSync has been updated recently but I haven't seen anything on the tickets page suggesting that it's saving settings locally so I won't retest it. Fortunately, I found a possible alternative: the archive synchronization function in 7-zip:

This would also resolve a feature request that's come up in the tickets area around archive large files split (very important for several cloud services including GoogleDrive and OneDrive).

The only problem with this is that the process must be run manually. However, there are some CLI tools that could be used to run for example every 30 mins or so: http://superuser.com/questions/528232/s ... nd-the-cli I have not tested this but hope to in the weeks ahead.

So this program put out a new version:

https://sourceforge.net/projects/crypts ... les/1.2.6/
http://www.softpedia.com/get/Security/E ... Sync.shtml

Some activity on the portable thread, but no movement on the part of the dev.

I seem to have a conversation where I make this point at least once a month:



... and the reason I keep trying to make a go of programs like CryptSync.

New version out: 1.3.2.358

No changelog, though it does seem to now support public-key encryption (GPG).

FYI, whatever changelog CryptSync has can be found at the Github repo: https://github.com/stefankueng/CryptSync/releases.

CryptSync homepage is https://tools.stefankueng.com/CryptSync.html -- old releases (up to v1.2.7) still at https://cryptsync-sk.sourceforge.io.

Why not to make a portable version of Cryptomator?

Update out (v1.4.2), although I wasn't able to find a changelog: https://github.com/stefankueng/CryptSync/releases

Nothing new on the portable front for this: https://github.com/stefankueng/CryptSync/issues/15
