Verifying SSL certificates

Standard transmission on the internet is way too unsecured, simply because of the open and decentralized infrastructure in its very nature. This means that communication is an easy target for eavesdropping. Business on the Internet is growing, the need for privacy, data integrity and confidentiality becomes critical, since business transactions typically involve sensitive information as personal data and payment card details.

SSL (Secure Sockets Layer) is a standard cryptographic protocol and security technology used for securing communications on the Internet and support authenticating of the communicating parties, SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser.

The other day, when I briefly wrote about the problems the faucet site Cointiply have had recently, I was in such a hurry I completely forgot to mention the tool I use to check those SSL certificates.
I use a free tool called SSL-labs, provided by Qualys, to check those sites I for some reason find suspicious or that seem to have a strange problem they should not have.
