@ -12,3 +12,9 @@ A2(x) = M2*x + C2
```
The combinations of (M1, C1, M2, C2) or (A1, A2) are not unique.
Two known (M1, C1, M2, C2), please reference [sm4 with AESENCLAST](https://gist.github.com/emmansun/ae4677d71c75ff8407d5f5b3a884f5d2), my question is how to generate all (M1, C1, M2, C2)?
```
{(M1, C1, M2, C2) | SM4-S(x) = A2(AES-S(A1(x)), A1(x) = M1*x + C1, A2(x) = M2*x + C2}
```
