Hill cipher decryption program

WebTo encrypt a message using the Hill Cipher we must first turn our keyword into a key matrix (a 2 x 2 matrix for working with digraphs, a 3 x 3 matrix for working with trigraphs, etc). We also turn the plaintext into digraphs (or trigraphs) and each of these into a column vector. WebCIPhER’s programming and services support the design, implementation, assessment, and continuous improvement of evidence-based educational practice. In similar fashion, …
