What is HTTPS?
HTTPS (Hypertext Transfer Protocol Secure) is the version of the web’s standard language (HTTP) that adds encryption, so the data you send and receive from a website is kept private and safe from eavesdroppers.
Let's break it down
- Hypertext: the text on web pages that can contain links to other pages.
- Transfer Protocol: a set of rules that tells computers how to move that text and other data over the internet.
- Secure: means the information is scrambled (encrypted) so only the intended computer can read it, protecting it from hackers or snoops.
Why does it matter?
When you browse, shop, or log into accounts, HTTPS stops strangers from stealing passwords, credit-card numbers, or personal messages, keeping your online life private and trustworthy.
Where is it used?
- Online shopping sites (e.g., Amazon, eBay) to protect payment details.
- Banking and finance portals that handle money transfers.
- Email services and social media platforms that store personal messages.
- Any website that asks for login credentials, such as email, forums, or cloud storage.
Good things about it
- Encrypts data, so it can’t be read by attackers.
- Verifies the website’s identity with digital certificates, reducing phishing.
- Improves search-engine rankings; Google prefers HTTPS sites.
- Builds user confidence, leading to higher conversion rates for businesses.
- Works automatically in modern browsers without extra setup for users.
Not-so-good things
- Slightly slower page loads because of the extra encryption steps.
- Requires a valid SSL/TLS certificate, which can cost money and need renewal.
- Misconfigured certificates can cause warning messages that confuse visitors.
- Older devices or browsers may not support the latest encryption standards.
