What is SSL?
SSL, or Secure Socket Layer, is a protocol or method for secure communication.
How does it work?
When a browser attempts to access the SSL-protected website, the browser and web server establish an SSL handshake which is a fairly quick process.
The server has to gain the client’s trust, so it sends the client a certificate. If trusted, the client builds an encrypted session key that will be used by the browser and server to encrypt all communication.
Server: You can trust me.
Browser: Let me check… Okay, I trust you. Here’s the key.
Server: Okay, I got the key. Let’s do this.
This is especially important if you plan to have anyone access TimeClock Plus from across the internet (from home or on the road). If you only plan to use it internally (across a network) then it’s not as critical, but it’s still a good security measure.
Any time you go to a website and notice the address changes to https, the “s” means that the website has this type of security in place.
How do you get a certificate?
Browsers will only trust certificates that come from a list of trusted CAs (certificate authorities).
