WebJul 14, 2024 · 1 Answer. Sorted by: 1. Assuming the $\frac {1} {11}$ is correct, you should replace it by $19$, as $11 \times 19 = 209 \equiv 1 \pmod {26}$ so that is the inverse of $11$ modulo $26$. So all entries get multiplied by $19$ so $3$ becomes $3 \times 19 \equiv 7$ etc. Recompute with the new matrix. WebJul 21, 2024 · The matrix used for encryption is the cipher key, and it should be chosen randomly from the set of invertible n × n matrices (modulo 26).
