If you want to have SSL verification installed and enabled on your site, but don’t want to spend the money on buying one because your site only need basic validation. Then, signing up to an StartSSL account is right for you.
StartSSL has been offering free SSL certificates for a long time. Yes, FREE SSL Certificates! This will only work if your site needs basic validation like domain and email verification. If you need higher level of validation, StartSSL also provide SSL certificates for those too. So visit StartSSL.com to sign up one.
Other company like RapidSSL also offer free trail SSL certificates, but only for an one month period. You can visit freessl.com to sign up for the free trail. We like using RapidSSL for our more higher level of SSL verification because it is cheaper then most companys like verisign or godaddy.
