    transposition cipher

    A cipher that encodes a message by reordering the plaintext. The receiver decodes the message using the inverse transposition. A simple kind of transposition cipher writes the message into a rectangle by rows, for example:
    Asimplekin
    doftranspo
    sitionciph
    erwritesth
    emessagein
    toarectang
    lebyrowsan
    dreadsitou
    tbycolumns
    and reads it by columns:
    Adsee tldts oirmo erbif tweab eymti rsrya cproi serdo lanta cosle ncegt wiuks iseas tmipp tinao nnohh ngnus.
    This type of cipher can be made more difficult to crack by permuting the rows and columns.
