PayPal IPN Upgrade to SHA-256 Encryption

PayPal announced that they would be upgrading their IPN encryption to SHA-256. This change may affect any merchant that currently uses PayPal's IPN system. Primarily, this is a server issue. The question is does your host's server support SHA-256. Although, to ensure that our extensions fully comply with the new change, we have made recent updates to Nice PayPal Downloads and Nice Membership for Joomla.
