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.
- Become a sponsor via Cryptomator's sponsors website.

Continuous integration hosting for ARM64 builds is provided by MacStadium.
Cryptomator offers 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, 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!! 🎉
- 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
- 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
For more information on the security details visit cryptomator.org.
- JDK 22 (e.g. temurin, zulu)
- Maven 3
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.
