## Features

  • Works with Dropbox, Google Drive, OneDrive, Nextcloud and any other cloud storage service which synchronizes with a local directory
  • Open Source means: No backdoors, control is better than trust
  • Client-side: No accounts, no data shared with any online service
  • Totally transparent: Just work on the virtual drive as if it were a USB flash drive
  • AES encryption with 256-bit key length
  • File names get encrypted
  • Folder structure gets obfuscated
  • Use as many vaults in your Dropbox as you want, each having individual passwords


  • 256-bit keys (unlimited strength policy bundled with native binaries)
  • Scrypt key derivation
  • Cryptographically secure random numbers for salts, IVs and the masterkey of course
  • Sensitive data is wiped from the heap asap
  • Lightweight: Complexity kills security


  • HMAC over file contents to recognize changed ciphertext before decryption
  • I/O operations are transactional and atomic, if the filesystems support it
  • Each file contains all information needed for decryption (except for the key of course), no common metadata means no SPOF

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
