The internet has revolutionized every aspect of modern society, from business to communication to entertainment. High-speed internet access worldwide means finding the information we want is easier than ever before. But these perks come with some downsides, too.
Security issues arise when data is exchanged over the internet. The world wide web relies on trustworthy entities to keep everyone's data safe. All major web browsers, like Google Chrome and Firefox, use SSL certificates to safeguard any data sent from web servers and maintain the trust of people surfing the internet.
Certificates like SSL certificate underpin online security and privacy during our online communications. Data pinged across the internet is kept safe through encryption. Encryption scrambles the data into something completely meaningless to anyone except the intended recipient (the only party with a secret key to access the data).
You might have thought that SSL if just for e-commerce sites to protect payments. That’s no longer the case. SSL certificates are invaluable for every website - because all websites have something of value for hackers: their reputation.
Internet users today are savvy customers, recognizing when a site uses SSL. This digital certificate increases trust in a company’s website, and ultimately of the company itself. Reputation proves a compelling argument for setting up a secure site. Whether you collect data or accept payments, authentication, confidentiality, and integrity are indispensable in all cases.
Certificate authorities (CA) are entities responsible for issuing digital certificates like SSL to websites. In layman's terms, a digital certificate is an electronic password that allows exchange data securely over the web using the public key infrastructure (PKA) - which we’ll come to.
