Best SSL Certificate to Use

[Atlanta-SMO]

I am setting up an ecommerce website that will sell batteries and like most e-commerce sites we will be taking credit cards.  I was exploring the different SSL certificates and providers and I was shocked at the difference in pricing.  Anywhere from free to over $1000!  What is really necessary and what is nice to have? Any suggestions on SSL providers?

Thanks

Hello Jimmy, I hope this answers you. There are a lot of SSL Certificate offers that I have seen so far and as a Marketer and a developer, I have implemented a lot of SSL Certificates. I will highly recommend you start with a Minimal SSL Certificate either from RapidSSL, GeoTrust or Comodo since they are cost effective.

I just ordered an SSL Certificate from Iwebhub. Check them out too.

Most SSL providers provide the same exact service. The difference in cost is from the levels of insurance, brand name and provider of the SSL, and trust factor of the badge. For example, you can buy a SSL from GoDaddy right now for around $70. As far as I can see it offers no insurance against identity or infomation theft. If you want a SSL from Verisign, its around $1000 and offers a $1,250,000 warranty. Most people know the verisign badge, and trust that their information will be encrypted and secure. When you purchase an SSL from them, you also get daily malware scanning and other features.

It really boils down to what are you getting the SSL for, if you require the additional insurance, what other features you would like to have, and if you think the badge will be the deciding factor of conversion for your users. If I remember correctly, the more expensive SSL's use a different bit rate. For example 128 bit vs 256 bit.

Hope this helps!

There's several different kids of SSL but it sounds like you're talking about a single domain. That narrows things down to the two most common kinds: domain validated and extended validation.

Domain validation is the most common kind of certificate. The certification authority will send an email to the administrative contact listed on the WHOIS of the domain. Typically it's a link and you click it and that's all that's involved. These are relatively inexpensive but only work for one domain or subdomain (i.e. the certiciate will be issued for www.domain.com but won't show as valid for domain.com). In this same vein, but more expensive, is the wildcard certificate, which works for all subdomains (*.domain.com).

Extended Validation is only available for corporations and you have to jump through a LOT of hoops to get one (birth certificate of one of your officers, letter of validity from your lawyer or accountant, etc.). They take some time to get but the advantage is that you get the coveted green bar (see PayPal's site for a good example).

It doesn't matter who issues the certificate. Verisign used to be a huge name in this area but not so much in recent years. You'll pay more for their name and "warranty", but I doubt anyone outside the industry itself could tell you who Verisign is, let alone what the difference is. I have two Godaddy certificates and it hasn't slowed us down one bit. Many people simply resell for another authority (i.e. GeoTrust, Comodo, etc)

The encryption itself doesn't differ between certificates. Your Private Key (the piece your server needs to decrypt the traffic) and Certificate Signing Request(CSR) will have to be at least 2048 bits in strength (industry-wide). The actual encryption between your server and your client's browser is something that is negotiated as part of the "handshake" when the connection is first made and is most likely 128 bits (although some browsers and servers can support 256 bits). One thing you will need to note is the difference between SHA1 and SHA2 (Godaddy directly asks you which you want and I'm sure the others do as well). When you look at a certificate's details in your browser you'll see who issued a certificate. If it says G2, they're using SHA2. SHA1 has some weaknesses and is being phased out. The only people who will notice the difference are people running Windows XP SP2 or earlier (running any browser, even Chrome or Firefox) and they'll get an invalid certificate warning.

Be sure that your host has plugged the Heartbleed bug or you'll expose your private keys (anyone with your private key can decrypt your traffic).
