Question

Which TLS Cipher Suites are supported with the Vonage Video API?

Applies To

• TLS Cipher Suites
• Video API

Answer

The Vonage Video API platform now supports TLS 1.3, in addition to TLS 1.2. TLS 1.3 support is available for both the OpenTok and Unified environments, and was enabled for the OpenTok environment on February 18, 2026.

For more details about supported TLS versions and security recommendations, see environment-specific documentation:

• OpenTok environment: https://tokbox.com/developer/guides/security/#security--transport-layer 

• Unified environment: https://developer.vonage.com/en/video/guides/security#security--transport-layer

On September 1, 2020, Vonage deprecated several older cipher suites supported by the Vonage Video API SIP Interconnect feature. These ciphers are used for SIP over TLS.

Since March 22, 2021, this deprecation has been extended to all Vonage Video API platform services that use TLS. See the list below for details of supported cipher suites and information about the removal of TLS 1.1 for supported TLS versions.

Supported Ciphers

Please see the lists below for supported cipher suites by environment and TLS version. The actual cipher suite used is negotiated during the TLS handshake and may vary depending on the endpoint.

OpenTok environment

If you are using the OpenTok environment, see the lists below.

Unified environment

If you are using the Unified environment, see the lists below.

EU proxy

The EU proxy uses the same cipher configuration for both the OpenTok and Unified environments.
