Download native binaries of Cryptomator on [cryptomator.org](https://cryptomator.org/) or clone and build Cryptomator using Maven (instructions below). ## Features - Works with Dropbox, Google Drive, OneDrive, MEGA, pCloud, 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 - Four thousand commits for the security of your data!! :tada: ### Privacy - 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](https://www.schneier.com/essays/archives/1999/11/a_plea_for_simplicit.html) ### Consistency - Authenticated encryption is used for file content 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](http://en.wikipedia.org/wiki/Single_point_of_failure) ### Security Architecture For more information on the security details visit [cryptomator.org](https://docs.cryptomator.org/en/latest/security/architecture/). ## Building ### Dependencies * JDK 19 (e.g. temurin) * Maven 3 ### Run Maven ``` mvn clean install # or mvn clean install -Pwin # or mvn clean install -Pmac # or mvn clean install -Plinux ``` This will build all the jars and bundle them together with their OS-specific dependencies under `target`. This can now be used to build native packages. ## License This project is dual-licensed under the GPLv3 for FOSS projects as well as a commercial license for independent software vendors and resellers.
