WeChall - Training: Crypto - Transposition I

Description:

Crypto - Transposition I

It seems that the simple substitution ciphers are too easy for you.
From my own experience I can tell that transposition ciphers are more difficult to attack.
However, in this training challenge you should have not much problems to reveal the plaintext.

Solution:

1. Here is a tool called "Transposition Cipher Solver".
   Reference:  http://tholman.com/other/transposition/
   
   
2. It's very easy for you to guess the first word in the cipher text is "Wonderful."
   oWdnreuf.l -> Wonderful.
   
   
3. So,  what we need to do next is to guess the length of the proposed key.
   Two Is Enough! :)
   
   
4. Here is what we have done.
   
   
   
   
   
5. Below is the results.

6. Now, read the letters from 1->0->1->0->1->0->...
   W->o->n->d->e->r->f->u->l->. ...
   
   
7. The original plaintext is :
   
   Wonderful. You can read the message way better when the letters are in correct order.
   I think you would like to see your password now: anpmhrdbogrs.
