How many rails should I use?

Typically 3-5 rails are used. More rails increase complexity, but too many rails relative to message length reduces effectiveness.

Are spaces and symbols encrypted?

Yes, as a transposition cipher that rearranges character positions, all characters including spaces and symbols are included.

Can it be combined with other ciphers?

Yes, combining Rail Fence (transposition) with Caesar cipher (substitution) and other ciphers can increase security.

FAQ

The Rail Fence cipher is a transposition cipher that places characters in a zigzag pattern across multiple rails and reads each rail in order to create the ciphertext.
