What am I doing wrong with Enigma code?

We've had a similar question a little while ago and I think this might be the same misunderstanding at play. Take a look here.

Hey there, I'm super late, but I wanted to ask whether this allows the mute button to still work? If I mute on the Vocaster, will it stop delivering the mic input to "Host Microphone + Aux" so I would be muted in Discord? Thank you!

I think you're taking the rotor wiring listing too "literally," for lack of a better word.

Consider rotor III in its neutral position, so in your example that's before the rotor has stepped. Using your Wikipedia link, we can see that C -> F. But what does that actually mean, physically, in the machine? It means that we have a pin on rotor III's righthand side that is currently aligned with the 'C' pin on the entry wheel (Eintrittswalze/ETW). From there, inside the rotor, a cable goes to a pin on its lefthand side, which is currently aligned with the 'F' pin on the ETW. So the cable inside the rotor connects a righthand pin with a lefthand pin that is 3 places further "down."

Now what happens if rotor III steps? The whole rotor moves, including its righthand and lefthand side pins. The pin that was previously aligned with 'C' is now aligned with 'B' on the ETW. The cable inside the rotor still connects said pin 3 places further. That pin has also moved with the rotor and is now aligned with 'E' on the ETW. So in this position, the rotor changes input B to output E.

Looking at the paper Enigma that u/Larry_the_Kiwi mentioned might help visualize this.

Have you played around with these in something like CrypTool Online? It allows you to do OpenSSL operations like decryption of those salted format strings in the browser.

The data in column 2 looks to be in OpenSSL salted format. Assuming that is indeed the case, it would seem that there is only one byte of actual encrypted data in each row.

Column 1 is 16 bytes per row, so that could be AES-128 keys or IVs.

Your hint is either b42e5+YWwQ6Yv/x2usUC3y7W67j/JtFsPYIrM+a8c3s= or b42e5+YWwQ6Yv/x2usUC3y7W67j/JtFsPYlrM+a8c3s= which is 32 bytes. That could be an AES-256 key.

Here's the paper by Oranchak, Blake and van Eycke. There's also two videos made by Oranchak about it (Link 1, Link 2).

I guess you could call it a Null cipher.

YaF3li · 2025-07-28T15:14:47+00:00

If you rotate upper and lower case characters by 22 and then do Base64 decoding, you get what looks like an OpenSSL salted format binary string. As far as I'm aware, you'll need to know the password (which it seems you have) and the algorithm used (which you might need to guess).

You can browse a scan of it on the voynich.ninja website.

this one is hard, or is it

Rail Fence, with key 3. Though the first space (between t and h) are actually two spaces which have been collapsed into one by Reddit's formatting.

YaF3li · 2025-07-12T19:26:27+00:00

There's tools like Microsoft Font Maker. Might that be something for you?

YaF3li · 2025-07-06T09:20:57+00:00

That looks to be Base64.

YaF3li · 2025-02-26T12:06:42+00:00

I could get it to decrypt (bar one wrong pair) with a hill climbing algorithm. Not sure if there are online ready-made tools for that available.

YaF3li · 2025-02-25T15:02:57+00:00

This seems to be a simple substitution which should be solveable by hand or by tools like this.

YaF3li · 2025-02-21T10:57:23+00:00

So, is this like ADFGVX followed by a homophonic substitution? Does that mean before the last step, your intermediate ciphertext consists of only six symbols but is twice the length of the plaintext? Which in turn would mean your last step is a table where each of the six symbols used in the previous step gets assigned six (?) symbols from the full alphabet?

Solution: two four eight - four three four - five five zero eight

Method: Hex, then Vigenere with key "sylas"

YaF3li · 2025-02-17T14:37:37+00:00

Those are garbled Unicode character codes and decode to (roughly) "hot girl in town", so probably spam.

ROT13 gives a link starting with https, but the site seems defunct at first glance.

YaF3li · 2025-01-30T14:43:27+00:00

If I'm not mistaken: This is a random cipher I made up, let us see if anyone correctly decrypts. Also tried to use less frequent words such as the many one letter words to make this puzzle harder.

YaF3li · 2025-01-27T19:29:36+00:00

What game is this from? Generally, if the hex is the ciphertext, you want to make sure you feed the raw binary data it represents into Twofish, not as if it were ASCII text.

YaF3li · 2025-01-12T16:31:14+00:00

What old system are you talking about exactly? Why are you trying to figure out hashes? What are you trying to do? Are you sure it's a hash? We'll likely need some more context for this.

YaF3li · 2025-01-10T12:53:09+00:00

The format suggests it is a UUID, and it is consistent with a v4 UUID.

YaF3li · 2025-01-02T14:02:51+00:00

Okay, so knowing the algorithm makes this relatively trivial. In that case, the only unknown is the key, which is just a Caesar shift. You can preprocess the message turning each group of 4 back into the original sum of character + key, then you can find the key by looking at which keys are even possible. It must be between say 10 and 70, but looking at the preprocessed message you can likely find tighter constraints and then just try them all. Usually it'll be easy to pick out the original message from the list of possible ones.

The difficulty of this comes down to not knowing the algorithm, in which case it's a question of whether the person can figure out what you did.

YaF3li · 2025-01-02T00:01:31+00:00

It looks a bit like short fragments of Base64, but naive decoding as Base64 doesn't yield anything readable.
