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

Once a visitor is on an SSL-protected page, the following visual indicators appear to show them that your site is secure and to give them the confidence to proceed:
- A “padlock” icon in the browser’s status bar
- The https:// prefix in the URL
- The URL address bar turns to green (Extended Validation Certificates only).
- The Trusted “Verified and Secure” site seal
