5.1 Security Considerations for Implementers

RTC APIs use the following security algorithms:

  • MD5 is used for key generation.

  • DES is used to encrypt the audio/video traffic.

The Session Description Protocol (SDP) Extensions do not require the preceding algorithms to be used; other key generation and encryption algorithms can be used. However, if interoperability with RTC API clients is required, DES has to be used for encryption.
