They are extremely important because you can use it to construct an attack that let you narrow down the number of guesses you have to do to recover the original key, so that it becomes feasible to crack the code. In general, leaking information about the key like this is almost a cardinal sin in cipher design, as it will give an opportunity for an attack. Modern ciphers will leak practically no information about the key.
- quelsolaar 13y agoTrue, if you want to brute force the algorithem you loose some bits by knowing that somewhere in the key there are 2 values that together become an xor. The question for me is if this information compounds over time. My thought was that it wouldnt since the key is modified.
