The Transposition Cipher

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

A transposition cipher rearranges plaintext characters rather than substituting them — writing a message vertically and reading it horizontally, for example — and the family is also called permutation ciphers.

Show

A message striped across rail cars and read down the train hides by arrangement alone.

Watch for

Every original character survives; only the order is the secret.
