comment uniqueness of the RSA public modulus
Though CodesInChaos referenced the answer earlier, with which I am quite content (thanks!), I would also like to thank poncho for interesting article!

comment AES key/ciphertext space sizes
Many thanks for your answer! I have to think more about it, but if it is OK to assume that if I have only one ciphertext block it is possible to have different encryption keys that could decrypt this single block (mapping P1 -> C1 can be the same for many permutations) then what is the minimum size of ciphertext I need to have to be sure what key was used for encryption (theoretically - assume I can wait for the search of the whole key space)-is there general rule for that? How is it called? And is there minimum size of ciphertext which ensures that the permutation was identified correctly?
