Dear Customer, Here at Assembly Payments we are always focused on ensuring our products and services are up to date with the latest security guidelines.
We are getting in touch to follow up on an email sent to you on the 31st of March 2020. If you have already replied then please disregard this email.
We are planning to implement an update that may affect you. This update relates to how your systems interact with ours specifically with regards to the ciphers used as part of HTTPS connections. We will be restricting the ciphers we accept for HTTPS connections to the following: - TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
Our prelive environment already has this change implemented and you can start testing if this change affects you or not. It is possible that your systems already use these ciphers in which case you do not need to implement any changes.
As we are planning to implement this change on the 30th of April 2020, we would greatly appreciate it if you could respond back to us by Thursday 16th of April, 2020 with one of the following: 1. When you would be able to test this change and inform us of the results 2. If you need more information or have any concerns with this change
Finally, we would appreciate you providing us the with your updated technical contact details (name, email and phone number)
