Cryptomator, an open source tool that encrypts files you upload to your favorite cloud service, has released version 2.0 of its iOS app.
The app remains open source and has a freemium version.
According to its website, Cryptomator “is a simple tool for digital self-defense. It allows you to protect your cloud data by yourself and independently.”
Cloud providers do encrypt data. However, most of them only encrypt the data during transmission. Others keep the decryption key to themselves; these keys could be copied, stolen, or misused. But with Cryptomator, “only you have the key to your data in your hand.”
