CryptoClub: Student Cipher Handbook

Author(s): JANET BEISSINGER, BONNIE SAUNDERS

CHOOSE FORMAT

The Student Cipher Handbook is the centerpiece of the CryptoClub curriculum. It is a student reference and workbook that is recommended for use in informal learning environments such as after-school or enrichment programs. It introduces ciphers in a way that encourages problem-solving and reasoning, and provides engaging messages to encrypt, decrypt, and crack. The Student Cipher Handbook can be used with whole-class instruction or with self-paced work in small groups.
