That's cool. Do that and add a shift to it and it would be hard to crack by hand if people didn't know you were shifting the letters.

What do you mean, shift it?    Like, capitalize?

Shift a's to b's and b's to c's or a's to c's and b's to d's. Like
Plaintext: Hello! How are you?
Shifted by 1 letter: Ifmmp! Ipx bsf zpv?
Shifted by 2 letters: Jgnnq! Jqy ctg aqw?

Something like that.

Oh lol
Yeah
And then z would be a
I'll try--
iu ff st fu j t b

I showed my friends this and they could never crack it. They got all mad.
Try this:
Na ocpi ju cqd

I'm not going to give out the algorithm because I'm pretty sure I'm the only person on the planet who knows how to decode it.

And I have an even harder version.

If it's a one-time pad, then yes, you are the only one that knows how to decode it unless you gave the key to someone else.

If you didn't use the one-time pad, then no one can decrypt that unless you give at least 20 more encrypted texts or the algorithm.

So if you don't give out the algorithm, it is currently impossible to decrypt.  Unless someone decided to try out every single algorithm, which then they'd be going through infinite algorithms plus trying to find the key at the same time.

The result is: no one here on Scratch can decrypt it.

Trying to make sure I cover all Twenty Six Letters In The Abc's.

All right I'll try this:
ete 're ntexsitn tixt

What type of algorithm are you using?

All I got from a shift search:

I don't see any real words in it.

It's in the post. It's obvious if you look carefully. (At least I assume it would be)

Hmm, I think I'm blind then. I can't seem to find it. I know 're is a hint, but I can't see any words that could end in 're with the letters given.

And what's in the post? The algorithm? All I see is a hint. :p

Website cannot be found.

I'm guessing you mean canyoucrackit.co.uk.

If you do, then:

Pff, I think you cheated. The challenge has closed.

Anyone have any codes they've created and want to strengthen ( even by a small factor )?

http://www.cryptool-online.org/ is a good place to learn more about Cryptography and Cryptanalysis.

N0BODY will crack this.

Is the plain text at least 25 characters?

Wow. Looking at all these codes, it really astonishing. I need to learn how to do this.

Yes.

Can you give the algorithm you used?

Not yet, but I'll tell you that I can decipher it and it uses 3 codes in a logical order.

No, don't post the answer, just post the algorithm. The point of this is to strengthen algorithms, not just post a blind cipher challenge.

If you post a blind cipher challenge, it should be at least a paragraph long.

This took me an hour.

OK, whoever decodes/deciphers this is REALLY good and should go to the CIA.
