![]() ![]() NCrypted Cloud is available for free for Windows, Mac, iOS, and Android. Business tiers are also available for a monthly subscription fee. NCrypted Cloud supports multiple cloud storage providers. It is currently compatible with Dropbox, Google Drive, Box and Egnyte. I have compiled a list of such encryption applications for your consideration. Find the one that best suits your needs, but be aware that if you ever lose your secret encryption key, that data will be lost to you forever. If you’re really serious about your privacy, but don’t want to shell out for more expensive packages, we have an alternative solution. In several apps, you can encrypt your data before uploading it to the cloud, ensuring that only you can decrypt your files. In fact, any user is able to do this, however, these applications are mainly aimed at accountants, lawyers, doctors and other professions that require a high level of confidentiality. Several cloud backup companies such as iDrive allow the user to create their own private key by encrypting the data on their local computer before uploading it to the cloud. But typically, this capability is reserved for a more expensive business-grade cloud service package, rather than for individual use. iDrive is currently offering a 75% discount on its 2TB package, making it a much more affordable option for just about anyone who wants to use it. Arcsnap is a unified Sync+Backup service that can be considered as a combination of Dropbox and Crashplan offering trustworthy security and one of industry’s lowest prices.Most cloud storage and cloud backup providers, such as Google Drive, Dropbox, Box and Microsoft OneDrive offer some level of encryption – essentially scrambling the contents of the files you upload. To decrypt them, an encryption key is required. Most cloud storage providers store the encryption key themselves instead of providing it to the user and thus require him or her to blindly trust that the company will not abuse access to your files, leak key data to hackers, or will pass it on to the monitoring authorities. Also, anyone with physical access to your phone or laptop can easily get into files in the cloud because most of these services leave you logged in by default. Sync Services like Dropbox, Google Drive, Microsoft OneDrive, etc. are widely used to seamlessly share files across multiple users or across multiple devices owned by an user. These Sync services are not a replacement for backups since if one of the devices malfunctions or if the user accidentally deletes some files/folders, the deletes are propagated to other users or devices. To protect against this, users are encouraged to use Backup Services like Crashplan which provide a consistent point-in-time snapshot of the entire folder hierarchy. While the Backup Services allow users to access the backups on other (mobile) devices they do not allow editing of a specific file/folder on multiple devices and so does not subsume the functionality of Sync Services. To be fair, Sync Services store a predefined number of file versions and allows users to retrieve a deleted file or an older file version. But in most retrieval use cases, recovery to an earlier snapshot of the folder hierarchy is preferable to retrieving individual files from their file versions. This is because most workflows utilize more than one file.įor example, a report may consist of some images, a presentation, a spreadsheet and a document and all the files need to be backed up as a consistent point-in-time snapshot. Also newer applications like iPhoto, iWork store their application data as a folder with multiple files and the folder snapshot approach is more appropriate than file versions. User InterfaceĪrcsnap shows up as a virtual drive on Windows, Linux and Mac OSX and integrates with Android KitKat 4.4 Storage Access Framework. Screenshot of the Mac OSX user interface is below. ![]() ![]() Most Sync services do not support file content encryption with a user-controlled encryption key. Layered products like Boxcryptor or Sookasa that work on top of Dropbox (say) provide both file name and file content encryption with user-controlled encryption keys. These products are more expensive than the Sync service. On top of this they use a proprietary encryption implementation that mandates the use of their software to decrypt and access the file content. This vendor-lockin is a non starter for most long-term secure file storage use cases.Īrcsnap does file content encryption using the OpenPGP format and imposes no vendor-lockin since file content can be decrypted using open source tools like gpg. Optionally, file name encryption is also supported using a simple HMAC-SHA1 scheme. PricingĪrcsnap has two operating modes selected during install time.Ī. ![]()
