I can describe how common ciphers work, and use them to encrypt and decrypt information.
Show transcript
Ciphers are used to encrypt and decrypt messages, turning readable text into unreadable ciphertext.
Common ciphers like the Caesar and substitution ciphers use patterns or keys to shift or replace letters in a message.
More complex ciphers use multiple shifts or a keyword, making them harder to break.
