What is SSL?
SSL, which stands for Secure Sockets Layer, is a security protocol that used to be the main way to encrypt data sent over the internet. While it has been superseded by its successor, Transport Layer Security (TLS), the term “SSL” is still commonly used for both.
Here’s a breakdown of what SSL/TLS does:
Encryption:
When you visit a website that uses SSL/TLS, the communication between your browser and the website is encrypted. This means that the information you send and receive, such as login credentials, credit card details, or personal messages, is scrambled and unreadable to anyone trying to intercept it. Imagine it as sending a secret message with a special code that only the recipient can decode.
Authentication:
SSL/TLS also helps to authenticate the website you’re connecting to. This means it verifies that the website is actually who it claims to be and not a fake imposter trying to steal your information. Think of it like checking the ID of someone before letting them into your house.
Data integrity:
SSL/TLS ensures that the data you send and receive is not tampered with during transmission. This means you can be confident that the information you see on the website is accurate and hasn’t been modified by anyone else.
How to tell if a website uses SSL/TLS:
- Look for the padlock icon in your browser’s address bar.
- Check the URL: websites using SSL/TLS will have HTTPS at the beginning instead of just HTTP.
Importance of SSL/TLS:
Using SSL/TLS is essential for protecting your privacy and security online, especially when you’re entering sensitive information like passwords or credit card numbers. While most websites you visit these days use SSL/TLS by default, it’s always a good practice to check for the signs mentioned above before entering any personal information.
