How DTLS and SRTP protect your data, and how to prevent VPN IP leaks in the browse
One of the most common concerns regarding WebRTC is the potential for "IP Leaks." Because WebRTC is designed to establish direct peer-to-peer connections, it must gather the user's local and public IP addresses. While this is necessary for functionality, it can expose a user's real location even when using a VPN.
The Role of the Browser Modern browsers like Chrome, Firefox, and Safari have implemented mDNS (multicast DNS) to hide local IP addresses, replacing them with randomized identifiers. However, the public IP remains visible to the peer.
Encryption: DTLS and SRTP It is important to note that WebRTC is secure by design. All media streams are encrypted using Secure Real-time Transport Protocol (SRTP), and the keys are exchanged via Datagram Transport Layer Security (DTLS). This ensures that even if a hacker intercepts the data packets, they cannot eavesdrop on the conversation.
Privacy Best Practices For developers, using a TURN server is not just a connectivity solution but also a privacy feature. By routing traffic through a relay, the end-users' IP addresses are masked from each other, providing an extra layer of anonymity.
