At the heart of CryptCode is the QRT: Quotient Ring Transform. The transform essentially converts a set of points on a polynomial to another set of points on the same polynomial, without ever computing the underlying polynomial.
The playground section of the application allows users who want to learn more about the Quotient Ring Transform to experiment with the transform itself. The playground operates over characteristic 2 (GF(2^n) with n in {8, 16, 32, 64}) as well as a choice of small prime fields.
