Merchants and partners use HTTPS to securely connect with PayPal’s servers. PayPal uses the Transport
Layer Security (TLS) protocol to encrypt these communications. To ensure the security of their
systems and adhere to industry best practices, PayPal is updating its services to require TLS 1.2
for all HTTPS connections.
To avoid any disruption of service, you must verify that your systems are ready for this
change by June 17, 2016 June 30, 2017.
While Encore Systems is no longer adding new features to our PayPal class libraries, we did not
want to leave our customers searching for a new solution when PayPal makes the switch to TLS 1.2.
Since we are no longer actively developing these libraries for the legacy Website Payments Pro,
we are now providing them free of charge. A license key is no longer required.
