'''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.<ref>{{Cite web |date=28 April 2020 |title=Encrypt Your Files Before Uploading it to Cloud With Cryptomator |url=https://itsfoss.com/cryptomator/ |access-date=2022-08-15 |website=itsfoss.com |language=en-US}}</ref> It is available for all major operating system including Android, iOS, Windows, Mac, Linux.<ref>{{Cite web |title=Flathub—An app store and build service for Linux |url=https://flathub.org/apps/details/org.cryptomator.Cryptomator |access-date=2022-08-15 |website=flathub.org}}</ref>
Cryptomator uses AES-256 standard encryption and WebDAV and relies on its open-source model for software verifiability, trust and bug fixing.<ref>{{Cite web |title=t3n – digital pioneers {{!}} Das Magazin für digitales Business |url=https://t3n.de/consent?redirecturl=%2Fnews%2Fcryptomator-cloud-verschluesselung-597606%2F |access-date=2022-08-19 |website=t3n.de |language=de}}</ref> The software encrypts each file individually.<ref>{{Cite web |last=A |first=Damián |date=2017-09-10 |title=Cryptomator, client-side encryption software |url=https://ubunlog.com/en/cryptomator-encryption-client-ubuntu/ |access-date=2023-04-08 |website=Ubunlog |language=en}}</ref>
==History== In 2017, Cure53 audited the software.<ref>{{Cite web |first=<!--Cure53, Dr.-Ing. M. Heiderich, MSc. N.

Tobias Hagemann, however, said this was a false positive.<ref name=":0" /><!-- "This is due to the Java Cryptography Extension, where the ECB mode must be specified for the creation of the SIV mode, even though this is and was never used by Cryptomator." -->
In December 2021, Cryptomator 2.0 was released for iOS, which was rewritten in Swift and integrated with the native iOS Files app.<ref>{{Cite web |date=21 December 2021 |title='Cryptomator' 2.0 is Here and it Integrates Into iOS Files App |url=https://www.macobserver.com/cool-stuff-found/cryptomator-2-0-is-here/ |access-date=2022-08-19 |website=The Mac Observer |language=en-US}}</ref><ref>{{Cite web |date=2023-03-13 |title=Cryptomator |url=https://apps.apple.com/us/app/cryptomator/id1560822163 |access-date=2023-08-23 |website=App Store |language=en-US}}</ref>
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.<ref>{{Cite web |last=Orr |first=Andrew |date=2022-01-11 |title=Update Immediately: Bug in 'Cryptomator' Leaks Encrypted File Paths to Apple |url=https://www.macobserver.com/news/bug-cryptomator-file-paths/ |access-date=2022-08-19 |website=The Mac Observer |language=en-US}}</ref>
