## Supporting Cryptomator
|
|
|
|
Cryptomator is provided free of charge as an open-source project despite the high development effort and is therefore dependent on donations. If you are also interested in further development, we offer you the opportunity to support us:
|
|
|
|
- [One-time or recurring donation via Cryptomator's website.](https://cryptomator.org/#donate)
|
|
- [Become a sponsor via Cryptomator's sponsors website.](https://cryptomator.org/sponsors/)

## Introduction
|
|
|
|
Cryptomator offers multi-platform transparent client-side encryption of your files in the cloud.
|
|
|
|
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
|
|
- Three 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
|
|
|
|
- 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](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 17 (e.g. temurin)
|
|
* Maven 3
|
|
* Optional: OS-dependent build tools for native packaging (see [Windows](https://github.com/cryptomator/cryptomator-win), [OS X](https://github.com/cryptomator/cryptomator-osx), [Linux](https://github.com/cryptomator/builder-containers))
|
|
|
|
### Run Maven
|
|
|
|
```
|
|
mvn clean install
|
|
# or mvn clean install -Pwindows
|
|
# 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.
|
|
|
|
### Start Cryptomator
|
|
|
|
If you unzip the buildkit for your OS, you will find a launcher script with some basic settings. You might want to adjust these to your needs. To start Cryptomator, simply execute the launcher script from a terminal, e.g. `launcher-linux.sh`, if you're on a Linux system.
