Step 2 - Transposition:This intermediate ciphertext then fills the columns (left to right) of a transposition matrix using the keyword"crime". Since "crime" consists of 5 letters the matrix contains 5 rows. Note that the matrix is filled up withAAA at the bottom right.C1FVADAR5XAFDDI3AFDVAM4VAVGAE2FXFFAThe final cipher is read as rows based on alphabetical order of letters of the key "crime":FVADA FXPFA AFDVA VAVGA XAFDDTo decode, the recipient sets up two matrices based on two keywords, first t
