I know that AES is secure against KPA. However, is it possible to generate a complete list of all possible keys that will work for a given block? If so, how?

    $\begingroup$ Define 'will work'. Naively I think all keys will 'work' in the sense you can encrypt or decrypt with them, and by doing so you can generate every possible 128-bit output from the same input block. $\endgroup$ – Rup May 13 '17 at 23:13
