I have been testing a cURL script for PayPal's IPN that used to work. Now I get the following error when trying to Postback to get validation (IPN): error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure. Do the HH servers support SHA256 as it looks like PayPal updated theirs earlier this year. Support SHA-256. PayPal is upgrading SSL certificates on all Live and Sandbox endpoints from SHA-1 to the stronger and more robust SHA-256 algorithm. You will need to update your integration to support certificates using SHA-256. Discontinue use of the VeriSign G2 Root Certificate. In accordance with industry standards, PayPal will no longer honor secure connections that require the VeriSign G2 Root Certificate for trust validation. Only secure connection requests that are expecting our certificate/trust chain to be signed by the G5 Root Certificate will result in successful secure connections. If they do not, when will they? Thanks.
