We are having the website (www.kalakendra.com) on magento v1.9.2.1 which hosted on the GoDaddy cloud server. We are using the paypal express checkout with IPN service. We have received an email from paypal concerning to upgrade the paypal ssl certificate security measures.
I have gone through various forums and stackoverflow questions as well. But still i have some doubt on the impact of paypal security upgrades if we fails to do it.
Our Server Configurations are
Linux 3.16.0-30-generic Ubuntu V14.04 MySql v5.0.11 Apache/2.4.18 (Unix) OpenSSL/1.0.2g PHP/5.5.34 mod_perl/2.0.8-dev Perl/v5.16.3
my doubts are,
Even though we don't have any SSL certificate but have the latest upgraded cloud server with openssl v1.0.2. So whether we should implement the SSL Certificate installation or no need of that?
Shall we can update the SHA-1 to SHA-2 and also VeriSign G2 Root Certificate to VeriSign G5 Root Certificate without having SSL certificate?
Sorry for my poor english.
Thanks.
