Security Update: Dynamic Media/Dynamic Media Classic TLS update

Hi,

This is regarding the Security Update for Dynamic Media/Dynamic Media Classic TLS update.

Adobe will be updating infrastructure to support further capabilities of Dynamic Media and Dynamic Media Classic (p.k.a Scene7). From 30th April 2024, the following protocols will no longer be supported: TLS 1.0,TLS 1.1, SSL 2.0, SSL 3.0, and the list of ciphers for TLS 1.2 mentioned in documentation links shared below.
AEMaaCS
AEM 6.5
DM Classic.
This will impact Dynamic Media on Experience Manager Cloud Service, Managed services, On-Prem, Dynamic Media Hybrid and Dynamic Media Classic. Making API calls to Dynamic Media using old TLS protocols/ciphers connections will be impacted. This will also affect delivery where a set of old Browser + OS combinations (mentioned in documentation) which communicate using older ciphers will be blocked for delivery for the organization's customers. You will need to upgrade TLS to make the API calls successful.

if we making calls to Dynamic Media in our application, how can we check which TLS protocols/ciphers are being used to make the call so we can update them if they are outdated?
