What is TLS?
Transport Layer Security (TLS) is an encryption protocol used to communicate between systems, which superseded the Secure Sockets Layer (SSL) protocol in 2000. TLS v1.0 has in turn been superseded by TLS v1.1, TLS v1.2 and TLS v1.3.
Per PCI DSS v3.1 and v3.2, SSL and early TLS (TLS v1.0 or TLS v1.1) are no longer considered strong encryption protocols, due to vulnerabilities in these protocols to which there are no fixes. TLS v1.2 and TLS v1.3 are currently PCI compliant.
How does it impact me?
Customers are required to support at least TLS v1.2 for their connection to the Open Payment Platform. TLS v1.0 and v1.1 are disabled since 2018. Customers who do not support at least TLS v1.2 will no longer be able to connect to the service. The list of ciphers that are supported is available below. Customers need to support one of the available ciphers from this list to continue connecting to the Open Payment Platform.
TLS v1.0 and TLS v1.1 are disabled for all online business tools, and for the eSupport portal. Customers are required to use a TLS v1.2 or TLS v1.3 compatible browser to ensure they can continue to access our online tools. It is recommended to choose TLS v1.3 as tests have shown that this can be up to 15% faster on the TLS Handshake.
If my organization’s connection does not support TLS v1.2, what do I need to do next?
If your connection to the Open Payment Platform uses TLS v1.1 or earlier, you will need to update your own systems to ensure that you are connecting using TLS v1.2 or TLS v1.3. Due to the vulnerabilities in older protocols, it is suggested that these changes are made as soon as possible. Below is a list of ciphers that are supported. Your organization will need to verify that your systems support one of the available ciphers from this list to continue connecting to the Open Payment Platform.
TLS v1.3 (suites in server-preferred order)
TLS v1.2 (suites in server-preferred order)
If your organization is not able to upgrade to TLS v1.2 or TLS v1.3 the service will no longer be able to connect to the Open Payment Platform . It is suggested that your organization test transactions in the UAT environment. Testing will ensure that your connection is successful or not.
If I am already using TLS v1.2 or TLS v1.3, do I need to do anything?
If your organization is already connecting to the Open Payment Platform using TLS v1.2 or TLS v1.3, and already using a TLS v1.2 or TLS v1.3 compatible browser, no action should be required.
