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.
