SSL (Secure Sockets Layer):
Digital certificates encrypt data using Secure Sockets Layer (SSL) technology, the industry-standard method for protecting web communications developed by Netscape Communications Corporation. The SSL security protocol provides data encryption, server authentication, message integrity, and optional client authentication for a TCP/IP connection. Because SSL is built into all major browsers and web servers, simply installing a digital certificate turns on their SSL capabilities.
Server certificates or SSL certificates are designed to protect you and visitors to your site. Installing a digital certificate on your server lets you:
- Authenticate your site. A digital certificate on your server automatically communicates your site's authenticity to visitors' web browsers, confirming that the visitor is actually communicating with you, and not with a fraudulent site stealing credit card numbers or personal information.
- Keep private communications private. Digital certificates encrypt the data visitors exchange with your site to keep it safe from interception or tampering using SSL (Secure Sockets Layer) technology, the industry-standard method for protecting web communications.
Virtually all web servers and the leading browsers are optimized and ready for SSL. To activate SSL sessions with visitors to your site, all you need is a digital certificate for your server.
- Identify visitors. If visitors to your site use personal digital certificates, your server can instantly recognize them, facilitating instant log-in (and preventing later repudiation of the web transaction).
- Prevent tampering. SSL preserves the integrity of every transaction, generating a warning if so much as one character of information is changed between your server and your customer's browser.
- Assure confidentiality. Users are assured that no unauthorized entity has intercepted data, like account numbers or credit card numbers, enroute to the intended destination.
