FAQs
What is SSL?
Secure Sockets Layer (SSL) is a protocol for enabling data encryption on the Internet and for helping web site users confirm the owner of the web site. SSL is most commonly used to protect communications between web browsers and servers. However, it is increasingly used for server to server communications and for web-based applications.
What is organization authentication?
Organization authentication, also known as business identity authentication, is a high assurance level of authentication. SSL Certificates with this level of authentication require verification of an organization’s existence through a government issued business credential. Usually VeriSign, Thawte or GeoTrust will get this independent verification by searching one of many government or private databases to which they have access.
What is encryption and why are there different levels?
Encryption is a mathematical process of coding and decoding information. The number of bits (40-bit, 56-bit, 128-bit, 256-bit) tells you the size of the key. Like a longer password, a larger key has more possible combinations. When an encrypted session is established, the encryption level is determined by the capability of the web browser, SSL certificate, web server, and client computer operating system.
How do web site visitors know if a web site is using SSL?
When a browser connects to a secure site it retrieves the site's SSL certificate and checks that it has not expired, that it has been issued by a Certificate Authority the browser trusts and that it is being used by the web site for which it has been issued. If it fails on any one of these checks the browser will display a warning to the end user. If it succeeds, several security indicators are built into modern browsers to indicate that SSL is enabled.
- The beginning of the URL or web address changes from http:// to https://
- A padlock on the browser window changes from open to closed
- The address bar will turn green and display the name of the web site owner when connecting to a web site protected by an Extended Validation SSL certificate.
In addition, a trust mark such as the GeoTrust Secured Seal may be added to web pages on a secure site
What does browser recognition mean?
When a browser or operating system encounters an SSL certificate, it checks to make sure that the certificate is valid and trusted. An SSL certificate is trusted if it is signed by a trusted or pre-installed root certificate. If a browser that does not contain the root CA certificate used to issue the SSL certificate, a security warning will alert them.
What is a certificate signing request or CSR?
A CSR is a public key that you generate on your server according to your server software instructions. (If you do not have access to your server, your web host or Internet service provider will generate it for you.) The CSR is required during the SSL certificate enrollment process because it validates the specific information about your web server and your organization.
What is a public/private key pair?
SSL uses unique cryptographic key pairs: each key pair consists of a secret private key and a related public key. Information encrypted with a public key can only be decrypted with the corresponding private key, and vice-versa.
