Cyberduck

Free, foolproof client-side encryption for cloud storage for the rest of us. We are thrilled to announce the availability of transparent, client-side encryption support for Cyberduck to secure your data on any server or cloud storage. The new encryption feature is based on the excellent concepts and work of Cryptomator. Encryption for data at rest prevents unauthorized access regardless of the server or cloud storage infrastructure.

Secure and Trustworthy

The Cryptomator security architecture has many crucial advantages over other client-side encryption solutions. Cryptomator encrypts file contents and names using AES. The passphrase for the vault is protected against bruteforcing attempts using scrypt. Directory structures get obfuscated. The software is open source thus can be audited independently for security – you can rest assured there are no backdoors and no hidden vulnerabilities. No online service subscription or account required with the risk of a service shutting down.

Interoperable and ready for use with any cloud storage

All vaults either created by Cyberduck, Cryptomator or their mobile apps for iOS and Android are fully interoperable. Previously, Cryptomator vaults could only be used with files on your local hard disk, thus limited to Dropbox or Google Drive services where data is locally synchronized with their client applications. Now, with Cryptomator support in Cyberduck, you can create secure vaults on any server or cloud storage available through the the broad protocol support in Cyberduck – including Amazon S3, Backblaze B2, Microsoft Azure and OneDrive or any OpenStack Swift, WebDAV or FTP interoperable hosting solution.

Transparent Encryption

Starting to secure your data is as easy as creating a new Cryptomator vault by selecting New Encrypted Vault and providing a passphrase. As soon as you try to open a folder containing a vault, Cyberduck will prompt for the passphrase to unlock it. Inside a unlocked vault you can work as you are used to with Cyberduck. Uploads and downloads are transparently encrypted and decrypted respectively with no change in your usual workflow required. You can have encrypted vaults and non-encrypted folders reside along on your storage location.

Mountain Duck 2.0 with support for Cryptomator vaults is available as beta today.

Cyberduck 6 will allow you to open a window to browse your local hard disk. Besides the obvious feature to drag files for download or upload to a remote server from within the application we have finally added a local browser to allow browsing Cryptomator vaults stored on your computer.

Update: We have updated our wiki with documentation to access Cryptomator Vaults on your local disk with Mountain Duck or Cyberduck.

The next major release of Cyberduck will support connections to Microsoft OneDrive. This includes support for both OneDrive Personal and OneDrive Business. You can give it a try in the current snapshot builds. Like our support for Dropbox, this allows to connect without synchronising files to your local computer.

This post is a reminder, that Cyberduck for Windows has been available in Chocolatey – a package manager for Windows – for some time. Chocolatey, some people want to call it apt-get for Windows, allows to install and upgrade software from the command line. Refer to the Cyberduck for Windows package information or just run choco install cyberduck if you are already familiar.

Mountain Duck 1.7 is now available with a focus on fixes for stability and performance improvements by an improved connection management. On Windows, the user interface is completely rewritten based on the Windows Presentation Foundation.

Mountain Duck 2.0 coming this spring will support transparent client-side encryption using Cryptomator interoperable vaults to secure your data on any server or cloud storage mounted.

We are thrilled to announce the availability of transparent, client-side encryption support for Cyberduck to secure your data on any server or cloud storage. The new encryption feature is based on the excellent concepts and work of Cryptomator. Cryptomator also offers apps for iOS and Android to access your encrypted data. All vaults either created by Cyberduck, Cryptomator or their mobile apps are fully interoperable.

Compared to other client-side encryption solutions on the market, ​the Cryptomator security architecture has many crucial advantages:

• Open source software that can be audited independently for security. You can rest assured there are no backdoors and no hidden vulnerabilities.
• In addition to file content encryption, file and directory names are encrypted, directory structures are obfuscated.
• Other than disk encryption utilities, each file is encrypted for its own.
• No online service subscription or account required. You will always have access to your data without the risk of a dependent service shutting down.

A  beta version is available for testing. You either download it directly for macOS and Windows or you switch to beta updates in your Cyberduck Preferences. Give it a try and let us know what you like and what you think – curious about your feedback! Support in Mountain Duck will follow later this month that will allow you to open Cryptomator Vaults in Finder and Windows Explorer.

Please note that this is beta software. For now, please use the Cryptomator Vault feature only with data you have a backup available.

Excited to announce Cyberduck 5.3 is now available in the Windows App Store with an easy, straightforward installation and automatic updates on Windows 10.

If you have installed macOS Sierra, you can now use tabbed windows in Cyberduck 5.2 or later. You might want to enable tabs by default when choosing File → New Browser by selecting in System Preferences the checkbox Dock → Prefer tabs when opening documents: Always. New browser windows and the transfer window will then be displayed in a single window frame with a tab bar. You can merge windows with View → Show Tab Bar and Window → Merge all Windows.
