WebThe Hill cipher is a multi-letter cipher. It is based on Linear Algebra operations, specifically matrix operations. It was created in 1929 by the mathematician Lester Hill. Some concepts you might want to revisit are matrix multiplication and inversion. The Hill cipher WebIn classical cryptography, the Hill cipher is a polygraphic substitution cipher based on linear algebra. Invented by Lester S. Hill in 1929, it was the first polygraphic cipher in which it was practical (though barely) to operate on more than three symbols at once.
