Long story short, a new way to represent cryptosystems like SHA2-256 was obtained which requires only a table of numbers, i.e. a fully linear matrix of coefficients. There is a precise way to use the matrix in question, and the result is that nonlinear systems can be modeled exactly in a linear way, if you no longer require the user to compute all outputs at once, but allow a more iterative use for the matrix.
Hopefully some fellow math nerds will be out there and will be excited.
Cheers!
