Create your own 2x2 Hill matrix, making certain that it is mod 26 (that is, its entries must be integers in the range 0 to 25) and that it is invertible mod 26. Use this matrix to encrypt the plaintext "zwickytf". Write down your matrix and its inverse. Again, make sure all of the entries are between 0 and 25 inclusive. Also write down the ciphertext in letters. Note about the Hill cipher: To multiply the encryption matrix and the plaintext vector, In other words, arrange the matrix and vector like this:

[e00e10e01e11][x0x1]=[y0y1] r codes and y0,y1 are the y0=e00x0+e01x1y1=e10x0+e11x1
