  1. Encryption

  2. What is Encryption? • Encryption: The process of coding text • Decryption: The process of decoding text Decryption is the opposite of encryption • A security method used to protect data • Files on computers • Data being passed through the Internet • ATM machines • E-Commerce • Facebook password

  3. Why Do We Use Encryption? • To secure important information e.g. : • Health records • Credit card information • Student records • Etc. • Prevents information from getting stolen or read • Without encryption, there is no reliable security

  4. How Does It Work? • Encryption allows the sender to transform data from plain text into ciphertext by using a key • Ciphertext: coded text • Key: what is used to encrypt and decrypt text • Two different types of encryption: • Asymmetric encryption (Public key encryption) • Symmetric encryption

  5. Pros and Cons

  6. Real Life Examples • Used in the military and the government • Now used in everyday life: • Online banking • E-commerce • Student records, health records, tax records etc. • ATM machines • Social networking (emails, texts, instant messengers) • Businesses
