The Department of Computer Science conducted Add-on Courses on Cryptography in 2022 and 2023. The duration of each course was of 30 hours.

Introduction to Cryptography

Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it. The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and e-commerce. Cryptography can be traced back to ancient Egyptian hieroglyphics, but remains vital to securing communication and information in transit and preventing it from being read by untrusted parties. It uses algorithms and mathematical concepts to transform messages into difficult-to-decipher codes through techniques, like cryptographic keys and digital signature to protect data privacy, credit card transactions, email, and web browsing. Modern cryptography techniques include algorithms and ciphers that enable the encryption and decryption of information, such as 128-bit and 256-bit encryption keys. Modern ciphers, such as the Advanced Encryption Standard (AES) are considered virtually unbreakable.

Cryptography has a wide range of applications in modern-day communication, including:

• Secure online transactions
• Digital signatures 
• Password protection 
• Encryption in WhatsApp 
• Encryption in Instagram 
• SIM card Authentication
