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.
