haxine / cryptomator Goto Github PK

Multi-platform transparent client-side encryption of your files in the cloud.

Download native binaries of Cryptomator on cryptomator.org or clone and build Cryptomator using Maven (instructions below).

• Works with Dropbox, Google Drive, OneDrive, ownCloud, 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
• One thousand commits for the security of your data!! 🎉

• 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

For more information on the security details visit cryptomator.org.

• Java 10 (min. 10.0.1, we recommend to use the current version)
• Maven 3
• Optional: OS-dependent build tools for native packaging (see Windows, OS X, Linux)
