Public group chats are not encrypted, private ones are.
That means that, if you’re signed into Element using both your PC and your phone, each will use unique encryption keys. Signal is secure.īuilt on the open source Matrix communication standard, conversations between individual Element users are strongly encrypted per device. Group chats, voice, video calls are encrypted. Additional devices have to be linked to the phone app. The service requires your phone number to create an account and you have to share this with users you want to chat to. Messages on Signal are end-to-end encrypted using the Signal protocol. Below you can find a quick guide detailing which common messaging services are end-to-end encrypted. This means that the only potential weak link in your security and privacy is the security of the device you’re using to send those end-to-end encrypted messages. If a service uses end-to-end-encryption, the keys to decrypt the messages are held only by participants in the conversation, so the messages themselves cannot be read by anyone until they get to your device. That means staff and contractors working with the service’s administration tools, anyone with sufficient authority in any country where relevant servers are hosted can demand that your messages be handed over, and anyone who illegally accesses the company’s systems could access and download your conversations. However, the message is decrypted when it reaches the server, which means that the server and anyone with access to its administrative functions could potentially read your messages.
