Have you ever seen URLs that start with http:\/\/ but also other URLs that start with https:\/\/. So where does that extra \u201cs\u201d come from and what does it mean? The technology that powers this little \u201cs\u201d is called SSL, which stands for \u201cSecure Sockets Layer\u201d. Let\u2019s find out what SSL is and what you need to know about SSL certificates. <\/span><\/p>\n

1. WHAT IS SSL? OVERVIEW OF SSL<\/b><\/h2>\n

1.1 What is SSL?<\/b><\/h3>\n

SSL (Secure Sockets Layer)<\/strong> is an Internet security protocol based on secure encryption between two systems. SSL was first developed by Netscape in 1995 to ensure privacy, authenticity, and data integrity in Internet communications. The two systems can be either a server and a client (e.g., a shopping site and a browser) or a server to a server (e.g., an application with personally identifiable information or payroll information).<\/span><\/p>\n

1.2 What is TLS?<\/b><\/h3>\n

TLS (Transport Layer Security)<\/strong>, transport layer security, is a more secure version of SSL. In 1999, the Internet Engineering Task Force (IETF) proposed an update to SSL. Since this update was developed by the IETF, it was renamed TLS. The difference between the final SSL 3.0 version and the first TLS version is not too big, the name change is to indicate the change in ownership. <\/span><\/p>\n

\"What<\/p>\n

SSL has not been updated since SSL version 3.0 in 1996. Most current Web browsers no longer support SSL. However, many security certificate providers refer to it as SSL certificates because this term is more commonly used and searched for by more people. In fact, when you buy SSL, you are buying a TLS certificate with ECC, RSA or DSA encryption options.<\/span><\/p>\n
