PayPal IPN Integration and Discontinued Use of VeriSign G2 Root CertfiicateAsked by C Coles on October 13, 2015 at 11:24 AM
PayPal notified us that we should contact all developers with whom we use IPN endpoints to ensure that they have discontinued use of VeriSign G2 Root Certificates and have updated their integration to support certificates using the SHA-256 algorithm. Is JotForm in compliance? We were notified that as of January 1, 2016, VeriSign would no longer be supported.

Our integrations with Paypal are fully optimized to SHA-256, on regards to VeriSign, let me send a note to our developers and they should give you a better response about this.
