Encryption is a technique used to protect digital information by converting it into a coded form. This ensures that only individuals with the correct "key" can access and read the information. Think of it like a secret lock—only those with the right key can unlock it and view the contents.
Firewalls act as security barriers between your private network and external threats. They monitor and filter incoming and outgoing traffic, blocking any suspicious or harmful activities. Think of them as digital security guards that ensure only safe data enters your network while keeping harmful threats out.
Authentication is the process of verifying the identity of a user or device. It ensures that only authorized individuals gain access to certain systems. This can be done through methods like passwords, fingerprint scans, facial recognition, or two-factor authentication (2FA), which adds an extra layer of security beyond just a username and password.
Encryption can be categorized into different types:
Symmetric Encryption: Uses the same key to both encrypt and decrypt the data. It’s fast but less secure if the key is compromised.
Asymmetric Encryption: Uses two different keys—one for encryption and another for decryption. This method provides stronger security, especially for communication over the internet.
HTTPS: Secure web connections that ensure all data transferred between your browser and a website is encrypted, making it harder for hackers to intercept.

This demo uses a Caesar cipher - each letter in your message is shifted forward in the alphabet by the number specified in the encryption key. For example, with a key of 3:
Online banks use encryption and multiple layers of security to ensure your money is protected. They rely on transaction verification systems and fraud detection algorithms to detect and prevent unauthorized access to your accounts.
Social media platforms offer various privacy settings and account security measures to protect user data. These include options to control who can view your posts, who can send you messages, and features like account recovery through email or mobile numbers.
Smart home devices can be secured through encrypted communication between devices and your network. Proper network segmentation and secure configurations are essential to prevent unauthorized access to your IoT devices and home network.
