Ill type a detailed response after breakfast. You can use this permutation cipher silver to check the key. Type natashaotomoski in the bottom box, the key where it says key, and hit decrypt.

I get what you're saying, sure. But just because a key exists that turns one phrase into another doesn't make that key meaningful.
If it was a 3- or 5-character key, that could be more meaningful. But there will always be a 15-character key that turns one 15-character phrase into another 15-character phrase. So it's basically irrelevant.
