Cryptomator – An Excellent Encryption Solution for Your Cloud Files

Cryptomator Encryption for Cloud Storage
Written by Martins Okoi
ADVERTISEMENTS

Cryptomator is an open source client-side encryption software with which you can encrypt the files you save with several cloud services. It is cross-platform (available for Linux, Mac, Windows, and iOS) and has an Android app on the way.

Cryptomator works excellently with Google Drive, Dropbox, Mega and other cloud storage services that synchronize with a local directory. And because the encryption is done on the client side, you can rest assured that no unencrypted data is shared with any online service.

With Cryptomator, you can create an unlimited number of vaults with unique passwords which will always be secure thanks to its 256-bit keys AES encryption method. Still on security, the directory structures, filenames, and file sizes get muddled while your encryption password is protected against brute force attempts using Scrypt.

Install Cryptomator in Linux

For Ubuntu “Vivid”, Mint “Sarah”, elementary OS “Loki”, or other distributions based on Ubuntu from 15.04 onwards can use the following PPA to install Cryptomator.
