Today Proton Technologies Ltd. presented a new feature in their portfolio.
Proton is a know swiss company who created a full End-to-End Encryption Mail service and VPN service.
The End-to-End Encrypted Mail service you can use for free and it is marked as open source.
Now Proton presented the new feature “encrypted contact manager”.
What is an Encrypted Contacts Manager?
ProtonMail’s new contact manager uses zero-access encryption in order to protect the details of your contacts. Zero-access encryption means that the protected contact fields are encrypted in such a way that only you are able to decrypt and read them, not even ProtonMail can read them. In our new encrypted contacts manager, the protected contact details are shown within an area with a lock icon.
