Encryption algorithms

Encryption is the process of changing the data into another form or code so that only people with access to a secret key or password can read it. For others, the message will not be in a readable form.

This KS3 Computer Science module introduces encryption algorithms to your students, explaining:

  • Encryption
  • Caesar cipher
  • Reverse cipher
  • Pigpen cipher
  • Modulo 2 encoding
  • Transposition cipher
