Can you translate it back?

I've got a little challenge for you.

ib jb eikybfi eite hvim

Can you translate this encrypted text back to its original form?

If you do, send me an email at math2001.contact@protonmail.com explaining how you found it, and I'll add you to the glorious list of people who found the solution πŸ˜„ (see below).

Rules

I guarantee you the original message:

  • contains only lower case ASCII letters (abcdefghijklmnopqrstuvwxyz)
  • has the same spaces as in the encrypted message. So you know that the first word will have 2 letters, the second one as well, the third one 7, etc...
  • can only translated to one string (the one I gave you)

They found it!

The glorious and amazing people who had a crack and found the secret message!

The list is over here.

Solution

Hey hey. Smart one, looking at the right place, πŸ˜„

I'll be posting the original message, as well as an explanation about how it worked on my blog next week, that is the Friday 1 June 2018.

Are we assuming a bijective mapping? I would assume not.

Na, we aren't assuming a bijective mapping (I had to google that one :laugh:).

In the case of a bijective mapping, every letter is always translated to the same letter. In this case, it isn't (but there's still a logic though).
