1. Encryption: SSL uses encryption to keep data secure while it is in transit. This means that any data sent between two computers, such as a web browser and a web server, is encrypted and can only be decrypted by the intended recipient. For example, when you visit a website that uses SSL, the data sent from your browser to the server is encrypted, preventing anyone from intercepting and viewing it.
2. Authentication: SSL also provides authentication, which means that you can be sure you are communicating with the intended server and not a malicious one. For example, when you visit a website with SSL, the browser checks the server’s certificate to make sure it is valid and from the correct server.
3. Data Integrity: SSL also helps to ensure data integrity, meaning that the data sent between two computers is not altered or corrupted during transit. For example, if you are sending sensitive information, such as a credit card number, SSL will ensure that the data is not changed or modified in any way.
