Decrypt TDRLTILTIEAEIYHVSIPWOAMWEIROTOILAIIDENORSSRTNULSTLMP

Decrypt TDRLTILTIEAEIYHVSIPWOAMWEIROTOILAIIDENORSSRTNULSTLMPIHDAAHHD using a rail-fence cipher:

there are no number of columns given so you have to use some trial-and-error to decrypt this message.

can you please help with providing steps so i can understand!

Solution

Rail fence cipher method is not so hard to crack. But doing that manually can take a long time if you don\'t know the rail. To do hit an trial choose the key, lets take it as 4.

Create table with 4 rows(as many as keys) with 60 column as length is 60.

You start by placing the \"T\" in the first square. You then dash the diagonal down spaces until you get back to the top row, and place the \"D\" here. Continue in the same way for first row. Once first row is completed, in second row place the character at the dash which is diagonal to T of first row. In this way continue for second row. Follow the same pattern for other rows also. Once all are filled read diagonally, that is the decryped text.
