We will be disabling TLS v1.0 completely in January 2017.

TLS 1.2 is strongly recommended as the latest and the most secure version. WSO2 API Cloud supports all 3 versions: 1.0, 1.1, and 1.2 - and we highly recommend that you switch to TLS 1.1 or 1.2 on your side to ensure secure communications. There's also some crypto issues in TLS 1.0, such as cryptographic initialization vectors (IVs) being predictable in some implementations as well. TLS 1.0 is the oldest version and is vulnerable in many implementations to well-known attacks such as BEAST and POODLE.

Both sides of the encryption channel can support any combination of these and negotiate the highest common standard at the beginning of the communication. There are 3 versions of TLS available at the moment: 1.0, 1.1, and 1.2. TLS is also sometimes referred to as SSL - the protocol that preceded it.

Transport Layer Security (TLS) is the encryption protocol used for secure communications between your API clients and API Gateway, as well as between the gateway and your service backend. If you are relying on TLS 1.0 - please make urgent changes to switch to version 1.2.
