What are Ciphers | Encryption and Decryption using Ciphers

In this lesson, we are going to discuss the answer to the question "What are ciphers?" We are going to learn the encryption and decryption using ciphers. Encryption is the process of using an algorithm to transform information into a format that cannot be read. Decryption is the process of using another algorithm to transform encrypted information back into a readable format. 🔔 Watch: Math in Communications Playlist ⏲️ Timestamps ⏲️ Introduction (0:00) Definition of Encyption and Decryption (1:35) Plain Text vs Cipher text (2:00) Objectives of Encryption (2:14) Substitution Ciphers (3:34) Pigpen Cipher (4:11) Monoalphabetic Substitution (11:29) Shift Cipher Encryption and Decryption (13:11) Atbash Cipher (17:24) Affine Cipher (20:35) Mixed Alphabet Cipher (28:54) Polyalphabetic Cipher (33:58) Vigenere Cipher encryption and decryption example (43:30) Want to watch more videos like this? 📺 SUBSCRIBE to my channel here: https://bit.ly/3fblF4F 🌐 Website: https://mathhubtutorial.com/mathvideotutorials/ 👍 Facebook: https://www.facebook.com/mathhubtutorials 🐦Twitter: https://twitter.com/mathhub303 🙋‍♂️ Have questions?
