• It is crucial for scenarios requiring confidentiality and integrity of media data, as it provides robust encryption and authentication without relying on a central server for key management
• Related to: webrtc, rtp

Cons

• Specific tradeoffs depend on your use case

ZRTP

Developers should learn and use ZRTP when building secure real-time communication systems, such as encrypted VoIP apps, video conferencing tools, or messaging platforms with voice/video features, to protect user privacy against interception

Pros

• It is particularly valuable in scenarios requiring strong end-to-end encryption without trust in intermediate servers, such as in privacy-focused applications or compliance with data protection regulations like GDPR
• Related to: sip, voip

Cons

• Specific tradeoffs depend on your use case

The Verdict
