Cryptomator

## 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 ### 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)
