TLS 1.2 Upgrade Technical White Paper


REVISED May 12, 2016Please note that the deadline for the TLS update has been moved out to June 2017

As a leader in Financial Technology, PayPal’s mission is to provide simple, affordable, secure and reliable financial services and digital payments. To accomplish this mission, we constantly evaluate our security posture – which includes complying with industry standards, laws and regulations – to create an environment our merchants and consumers can trust.

Beginning June 2017, PayPal will begin the process of discontinuing support for TLS 1.0 and 1.1, meaning that all communications with PayPal API (including SDK) must use TLS 1.2.

You can read more about PayPal’s official position on mandating the TLS 1.2 upgrade, the rationale for the upgrade as well as resources for merchants and developers to help them through the upgrade process by downloading the Foundation for June 2017 TLS 1.2 Upgrade Technical White Paper.
