For a recap of how the Hill cipher works, see here. 2 by 2 Case § Because the Hill cipher is linear, we only need to find 2 bigram correspondences to determine the key matrix. For example, if we knew that 'th' was encrypted to 'gk' and 'er' was encrypted to 'bd', we could solve a set of simultaneous equations ...

Notice, for example, that changing the plaintext block he to ie changes the ciphertext block from GV to JA. Decryption
WebFeb 10, 2024 · 5) I solved the equation K = C ∗ P − 1 (mod 26) I repeated these steps for many different mappings to "th" and "he". Sometimes I could not invert P and sometimes the K was invalid. Looking at the ciphertext I believe it is very likely that "th" -> "ut", since it appears at the beginning of so many 3-letter words.
