Encrypting Files on GreenAnt nest is possible using client-side encryption.

To be accessible form the web interface, files are not encrypted on the server by default (encryption at rest). However, you can use client-side encryption if you want an extra layer of protection for your files (for example with encFS. GreenAnt also supplies a fully encrypted storage system called GreenAnt GCrypt. Please contact us if you need advice regarding file encryption, we'll be happy to recommend solutions which fit your use case.

Using encFS

encFS allows you to create an encrypted storage for your files that can only be decrypted using a locally stored password. It's important you don't lose this password, as there is no way to recover it. We recommend using a password storage application like KeepassX to store your passwords.

  • Strengths of encFS
    • ease of use, works file-by-file
    • compatible with cloud storage
    • strong encryption
    • client-side
  • Weaknesses of encFS
    • vulnerable if multiple versions of files kept (we recommend clearing old versions of important files)
    • does not hide the folder structure (but does encrypt file names)
  • Alternatives to encFS
    • for users requiring a higher level of security, we recommend our advanced product GreenAnt GCrypt
