Description: A server certificate is a digital certificate that authenticates the identity of a server and enables an encrypted connection.
History: The concept of digital certificates dates back to the 1990s when the first security protocols for data transmission over the Internet were developed. The SSL protocol was introduced by Netscape in 1994, and its evolution led to the development of TLS in 1999. As the web grew, the need to secure communications became critical, driving the adoption of server certificates by websites to protect user information.
Uses: Server certificates are primarily used to secure online communications, especially on websites that handle sensitive information. They are essential for the operation of HTTPS, which is the secure version of HTTP. Additionally, they are used in secure email applications, VPNs, and in the authentication of devices on various networks.
Examples: A practical example of a server certificate is the one used by a bank on its website to enable secure transactions. Another example is the certificate used by an online store to protect its customers’ payment information during the checkout process.
