An SSL certificate serves as an electronic "passport." It establishes the website's authenticity and credibility and enables the browser and Web server to build a secure, encrypted connection.
Credibility is established by checking the digital certificate, which includes:
• The Certificate holder's name (individual or company)*
• The Certificate's serial number and expiration date
• A copy of the Certificate holder's "public" cryptographic key
• The digital signature of the Certificate-issuing authority
• Extended SSL Certificates give the site visitor an additional visual cue, displaying the Certificate holder's name against a distinctive green background in the visitor's browser bar.
