Krynapsis

Mobile learning through visual cryptography.

Krynapsis is an Educational Technology (Mobile Learning) that allows users to encrypt and decrypt plain text and digital images. This app in intended to Educational purposes. To decrypt an image or a plaintext a key is needed. The key is a modular inverse of a square matrix. The user has to input the modular inverse matrix of the original key to Krynapsis. So, the user has to calculate the modular inverse matrix of the matrix given by the application.

The goal of Krynapsis is the teaching modular inverse matrices calculation through visual cryptography.

The modulo of matrices used for plaintext encryption is equals 82.

The modulo of matrices used for image encryption is equals 256.

Learn and have fun by practicing maths in a significant context as Vygotsky, Piaget, Rabardell and Ausubel recommended.
