EV certificates assert a link between a certificate and an organization using a more thorough vetting process than OV certificates. The body issuing the certificate must validate the legal and physical existence of the organization. OV certificates assert a link between a certificate and an organization. Organization Validated (OV) Certificates.

Projects like Let’s Encrypt, which provides free certificates and automates the process of creating and installing them, rely on domain validation. DV certificates assert a link between a certificate and a domain. SSL certificates are generally divided into three types:
The public key needed for the encryption.Issue and expiration date of the certificate.Which certificate authority issued the certificate.Information about the holder of the certificate.The domain name the certificate is valid for.Anyone with the public key can use it to encrypt a message, but only the corresponding private key on the server can decrypt it.ĭepending on the type of certificate it also provides a visitor with information about the holder of the certificate: The public key is not secret and anyone can see it, so it doesn’t matter if it’s intercepted. A website visitor’s browser gets the public key necessary to open an encrypted connection from a server’s SSL certificate. SSL encryption is possible because of the public-private key pairing that SSL certificates facilitate. Equally, if a website does not have a certificate, that does not mean it cannot be trusted. Evil websites, like phishing sites, can have SSL certificates and you can establish safe, trustworthy connections to evil sites using SSL!ĭespite lots of (now outdated) advice, SSL certificates and padlocks should not be used as an indicator that a website is “safe”. Not every website that has an SSL certificate can be trusted. It does not make the website more trustworthy though, only the communication between it and you. This is particularly important when you are exchanging private information like credit card details or passwords. On the web, SSL makes a connection to a website more trustworthy: You are talking to the website identified in the certificate, and nobody is listening in or tampering with the communication between you. It ensures that a connection between two computers is encrypted. It authenticates the identity of the computer you are talking to. SSL certificates serve two important purposes: An SSL certificate is a digital certificate that authenticates a website’s identity and enables an encrypted connection. SSL is a security technology for establishing an encrypted link between a server and a client, such as a website and a browser, or a pair of email servers.
So, in this article we’ll use SSL to refer to the entire SSL/TLS family of protocols. On a strictly technical level, SSL was actually superseded by Transport Layer Security (TLS) many years ago, but the name has stuck around. Let’s start with some definitions and explain some of the terminology. Although the padlock may soon be hidden from view, certificates aren’t going anywhere. Secure Sockets Layer (SSL) certificates are what cause your browser to display a padlock icon, indicating that your connection to a websites is secure.
