WebThis instruction manual explains how to use Hill’s 2-cipher technique. Enciphering a Message 1. Obtain a plaintext message to encode in standard English with no punctuation. In this example, we will encipher the message DR GREER ROCKS. 2. Create an enciphering matrix: 2.1. Form a square 2x2 matrix with nonnegative integers each less than 26. 2.2. WebFor our example key matrix: So, modulo 26, the determinant is 25. Since this has no common factors with 26, this matrix can be used for the Hill cipher. The risk of the determinant having common factors with the modulus can be eliminated by making the modulus prime.
