Cryptomator

What is Cryptomator?

Cryptomator is an open-source software tool designed to provide encryption and privacy for cloud storage services. It allows users to create an encrypted vault or folder within their cloud storage accounts, like Dropbox, Google Drive, OneDrive, or any other cloud service that syncs with a local folder on your computer.

The primary purpose of Cryptomator is to ensure that your data remains secure and private, even when stored in the cloud.

Cryptomator provides an extra layer of security for your data in the cloud, ensuring that even if your cloud storage provider were to experience a data breach or unauthorized access, your files would remain encrypted and inaccessible without the correct password. It’s a valuable tool for those who prioritize data privacy and security when using cloud storage services.

How does Cryptomator works ?

First, you need to create an encrypted vault using Cryptomator. This vault will be a special folder where you store the files you want to secure. You specify the location of this vault on your local hard drive.

Client-server encryption: When you copy files to this vault, Cryptomator automatically encrypts those files before uploading them to the online storage service of your choice. Encryption is done client-side, which means your files are encrypted on your computer before being transferred to the remote server. The remote server only sees encrypted data and cannot access the contents of your files.

Individual encryption: Cryptomator encrypts each file and folder individually. This means that even if an attacker manages to decrypt one file, they will still not have access to the contents of other files in the vault.

Secure Access: To access your encrypted files, you must unlock the vault by entering a password. This password is essential for decrypting files. It should only be known to you.

User Interface: Cryptomator provides a friendly user interface that allows you to manage your vaults, view and add files. You can access your encrypted files as you would normal files.

Metadata Protection: In addition to encrypting data, Cryptomator also protects metadata, such as file and folder names. This further enhances the confidentiality of your data.

Cross-Platform: Cryptomator is available on various platforms, including Windows, macOS, Linux, Android and iOS, which means you can access your encrypted files from different devices.
