What is Cryptography in Simple Terms?

Cryptography is the science of securing information through techniques like encryption and decryption. It ensures that only the intended person can access the data.

For example:

When you send a WhatsApp message, it is encrypted before leaving your phone.
When the recipient opens it, the message is decrypted using a secret key.

This is how end-to-end encryption ensures privacy in communication.

By choosing cryptography projects, students get to work on the same technologies used in:

Online payments
Cybersecurity tools
Secure cloud storage
IoT devices
Blockchain applications
