Cryptomator

Most cloud providers encrypt data only during transmission or they keep the keys for decryption for themselves. These keys can be stolen, copied, or misused. Thanks to Cryptomator, only you have the key to your data in your hand. Cryptomator allows you to access your files from all your devices. It's easy to use and integrates seamlessly between your data and the cloud.To start with Cryptomator, you assign a password for a folder - we call it a vault - within your cloud. That is all.

No complicated key creation, no registration, no configuration! To access the vault, simply enter the password again. You will be provided with a virtual encrypted drive to which you can move your data - just like a USB flash drive. Every time you store something on this drive, Cryptomator encrypts the data automatically. Pretty simple, right? The technology behind this is state-of-the-art and encrypts both files and filenames with AES and 256 bit key length.
