We also turn the plaintext into digraphs (or trigraphs) and each of these into a column vector. If down around 3 or so, you might want to switch to a higher quality matrix. To 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). If it's up around 6-7 or higher, you might consider using a lower quality matrix and doing the encode over again. Don't apply a Caesar cipher to the original message instead of a transposition cipher, as then both steps can be combined to one Vigenère step and the ciphertext isn't stronger protected. When done the encoding run the MPV/M2V through Tecoltd Bitrate Viewer and check the average Q-level. Even if decoded, without knowing the result has been ciphered before the Vigènere cipher is used, it will still appear to be gibberish.
HOW TO ENCODE A MESSAGE WITHOUT A MATRIX SOFTWARE
You can automate this with appropriate software for visual programming and check whether you did it correctly.Double check to make sure you encipher correctly.An erroneously enciphered text can be impossible to interpret correctly, and it is difficult to recognize a mistake without a double-check.
