Cryptomator is open source encryption software that provides encryption for cloud drives. It provides transparent, client-side encryption for personal cloud storage. Cryptomator encrypts each file separately and then allows the user to sync files with a cloud or local storage of choice. [3] It is available for all major operating system including Android, iOS, Windows, Mac, Linux. [4]

Contents

Cryptomator uses AES-256 standard encryption and WebDAV and relies on its open-source model for software verifiability, trust and bug fixing. [5] The software encrypts each file individually. [6]

History

In 2017, Cure53 audited the software. [7] [8] Cryptomator was lauded for its high degree of robustness in cryptographic implementation, but criticized use of AES in insecure ECB mode. Tobias Hagemann, however, said this was a false positive. [8]

In December 2021, Cryptomator 2.0 was released for iOS, which was rewritten in Swift and integrated with the native iOS Files app. [9] [10]

In January 2022, an update was released for a bug that leaked file path to Apple, because of the integration with Apple's file and use of File Provider Extension API. [11]

Reception

Cryptomator received the CeBIT innovation award in 2016 for "Usable Security and Privacy". [12] [13]
