The provided document details an assignment that requires students to decode two different types of ciphers: Caeser cipher and substitution cipher. The first part involves deciphering a code by shifting 3 places in the Caeser cipher, followed by decoding the value from the resulting encrypted text using the same shift. The second part involves decoding a message from a substitution cipher using the given key. Students must apply their knowledge of ciphers to accurately decode the messages and arrive at the final decrypted texts.
