Answer:
1. With a key of '51423', what is AMSCO plaintext for the ciphertext version of: rkiesletitdiolcacuyth
Additional information:
For the AMSCO cipher, we take alternative two letter and one letter occurances, and then fit to a grid with a sequence key. With a key of '32415', what is the AMSCO plaintext for the ciphertext version of: 'nwrertht bapng kiereguo'? In this we have 21 characters so it will be laid out as: X X X X X 2 1 2 1 2 1 2 1 2 1 2 1 2 1 First we lay out the key, and then populate the first column: 3 2 4 1 5 n wr e And now the next column: 3 2 4 1 5 r n th wr t e And next: 3 2 4 1 5 ba r n p th wr ng t e And next: 3 2 4 1 5 ba r ki n p th e wr ng t re e And finally: 3 2 4 1 5 ba r ki n gu p th e wr o ng t re e And the result is "barkingupthewrongtree"
