Encrypted Text: ewzdsaqet

The only clue I've been given is there are no numeric values.

I'm not all that good with this stuff, so could really do with a hand.

More Info: the cipher was self created with concepts from a lot of different cipher algorithms, there is not tool online that will decrypt it

My friend made it in college! Here's what he sent me in full:

Background: When I say just started I don't mean we looked at Ceasers cipher and implemented it, we went threw a lot of the history starting with the enigma code and progressed from there to present day.

Clue #1:

There are no numeric values

Clue #2:

This is a word that is in the Oxford English Dictionary

Clue #3:

ASCII binary

    $\begingroup$ (oops, hit enter too early) ... then that's answering a question ("how do I make a cipher puzzle fun to solve?") that isn't yours ("what is the answer to this cipher puzzle I don't know how to solve?"). $\endgroup$ – Gareth McCaughan Sep 30 '16 at 10:42

    $\begingroup$ Let's consider the Enigma code mentioned by your friend. The folks at Bletchley Park knew the complete design of the Enigma machine. They had a bunch of outrageously smart people. They were working on it full-time, with winning a war for motivation. They often had extra information to help them (e.g., particular words that were likely to occur). I think the shortest message they ever managed to decrypt was about 90 letters long. $\endgroup$ – Gareth McCaughan Sep 30 '16 at 11:14

    $\begingroup$ @greenturtle3141 Because the question itself is bad. I really hope "My friend gave me this cipher" isn't a valid reason to prevent downvotes... $\endgroup$ – user14478 Sep 30 '16 at 23:48

I think your friend needs to educate himself a little more about code cracking and decryption techniques. If he does, he will realize that it is impossible for someone to "decrypt" a nine-letter message with none of the following:

  • what the plaintext might contain
  • what type of cipher was used
  • potential keyword(s) (if applicable)
  • a significant amount of encrypted text

The solution could literally be any 9-letter word in the English language.

If your friend really wants to give a legitimate code-breaking puzzle, have him supply you with several paragraphs of encrypted text, and then you might have a chance at breaking it.

  • $\begingroup$ there are only $26^9+26^8+26^7+26^6+26^5+26^4+26^3+26^2+26^1$ different Vigenere keys, but each one results in things $\endgroup$ – garr890354839 Oct 24 '16 at 17:40
