![]() ![]() Then (obviously only if you got the password right) the decrypted version gets mapped to drive X: (or what ever you chose when setting up this vault on your computer) and a file explorer window opens, showing the vault’s decrypted content. When you want to access a vault’s data, you start the Cryptomator app, select your vault, enter the vault’s password and click on “unlock vault”. So if you want to share a different set of files with a different group of people, you need to create/use a different vault with a (most likely) different password. Every user is using this same password for this vault. You can share a vault with others by sharing access to the (cloud) storage and telling them the password of the vault. If someone (maybe you on a different device) is sharing a vault with you, you can’t create it (the other guy already did that), but instead “open” it, specifying the directory from your point of view.Įxample (on Windows): the encrypted data will reside in C:\Users\Yourname\Dropbox\confidential_stuff\ with its decrypted version being visible (and editable) as drive X: Within the app, you select that directory, assign a password and an optional drive letter. A vault is essentially a directory, usually located inside your cloud app’s synchronization space. Then you set up a vault (or several vaults). Only use this source, as there are malware-ridden fake copies around. One time setupĪt first you download and install the app from. So easy, they won a special prize for Usable Security and Privacy on the CeBIT Innovation Award 2016 (“joint venture” of the German Federal Ministry of Education and Research and the large annual IT exhibition CeBIT Hannover). For details see the project home page and the documentation. ![]() Beta versions are available for iOS and Android. In early 2016, a group of Germans (why so often them?) published Cryptomator, a free, open source app, to provide automatic, transparent, client-side file-by-file encryption of entire directories, including files, subdirectories etc.Ĭryptomator is available for Windows, Mac and Linux. There is version 2 now, but it is relatively expensive, especially if you are using it in a business context. The solution is an app that encrypts each file individually, transparent to the user.īoxcryptor used to be known for this, but around 2012 a cryptographic flaw had been uncovered in the foundation (encFS) of their version 1. When another user starts opening the container before the first user has finished packing/uploading and the next user has finished downloading, the entire container file will be flagged as a conflicting copy, resulting in lots of manual effort to reconcile the changes. In a cloud sharing setting, only one user at a time can open the container for writing.A small change in data, like adding a contact or fixing a typo, results in transferring the entire container, which could be Gigabytes.The mounting/unmounting or unpacking/repacking steps are cumbersome to repeat before and after each editing session.Using a VeraCrypt container or an encrypted ZIP file would solve the trust issues, but has disadvantages in handling: But you did not dare to use cloud storage, because your data is confidential and you don’t want the cloud storage provider to read it. Most likely, you have been looking into using cloud storage to synchronize, share or backup data. Cryptomator is a relatively new, free (pay what you want), open-source program that offers transparent, automatic, file-by-file encryption. Container methods, packing many files into one encrypted container file, like VeraCrypt or ZIP, have disadvantages. File encryption apps should have first- or third-party support for mobile platforms.When you want to store confidential data on less trusted (cloud) storage, you need to encrypt it.Operating System ( FDE) encryption apps should utilize hardware security such as a TPM or Secure Enclave.Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page. Our best-case criteria represents what we would like to see from the perfect project in this category. Internal ( OS) disk encryption apps must be cross-platform or built in to the operating system natively.External disk encryption apps must support decryption on Linux, macOS, and Windows. ![]() File encryption apps must support decryption on Linux, macOS, and Windows.Cross-platform encryption apps must be open-source.There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress. If you have any questions about our criteria, please ask on our forum and don't assume we didn't consider something when making our recommendations if it is not listed here. We are working on establishing defined criteria for every section of our site, and this may be subject to change. ![]()
