How do certificates work for dummies?
The SSL certificates work using the Public Key Infrastructure (PKI) technology. This cryptography technique uses two keys, viz. a private key and a public key, that helps to encrypt the communication taking place between the two systems. The user sends a message to the server that is encrypted using the public key.
Tracking can be defined as collecting data points over multiple different web pages and sites, which can be linked to individual users via a unique user identifier. A cookie is a small text file that is stored on your computer or mobile device for a certain period of time when you visit a website.
Are certificates secret?
No. The certificate plus its digital signature is used to verify that the certificate belongs to the server. The digital signature is created with the private key.
What are two other names of digital certificates?
Types of Digital Certificates
- TLS/SSL Certificate.

- Client Certificate.
What does SSL stand for?
Secure Sockets Layer
Secure Sockets Layer (SSL) is a standard security technology for establishing an encrypted link between a server and a client—typically a web server (website) and a browser, or a mail server and a mail client (e.g., Outlook).
Cookies are small packets of data which a server can send to your browser to store some configuration or personal data. The browser automatically sends them along with all requests to that same server. The contents are usually very interesting to hackers, so it’s important to know how to secure these cookies.
Cookies that expire at the end of a browser session (normally when a user exits their browser) are called ‘session cookies’. Cookies that can be stored for longer are called ‘persistent cookies’. PECR applies to both types. Session cookies allow websites to recognise and link the actions of a user during a browsing session.
What are HTTP cookies and how do they work?
HTTP cookies currently in use are governed by the same origin policy that directs Web browsers to allow cookie sharing only between Web sites in the same DNS domain. As Web applications get richer, data sharing across domain boundaries becomes more important.
Can cookies be used to identify a person on a website?
The cookies and tracking in use on your website: This goes for both first-party and third-party cookies in use on your website. All cookies that directly identify a person or can potentially be combined to identify a person may only be used once you have your user’s proper consent to it.
