It's cool that you're interested in cryptography and history! :-)
Alan Turing is one of the most underrated geniuses of the 20th century. I recommend the movie "The Imitation Game", which gives a beautifully dramatised account of parts of his life. I wouldn't be able to type this (on a modern computer/phone) right now, if it hadn't been for him (and others of course). Unfortunately, I'm no Alan Turing.
And you're right, even he would have a hard time breaking your ciphers.
It doesn't really help at all that you posted the Enigma emulator that you used. Any good cryptography scheme should satisfy a very important condition:
"Neither knowledge of the key nor of the process of encryption shall be sufficient (individually) to break the encryption."
Enigma satisfies this standard to a high degree. The machine itself (without the key) is (pretty much) useless for decrypting messages known to have been encrypted by Enigma. And the key itself (without knowing that the message was encrypted by an Enigma machine) is useless as well.
Both the process of encryption and the key must be known simultaneously to decipher a message.
That's why the Website alone doesn't help me at all. It is a (emulated) Enigma machine, but it's (nearly) useless without knowledge of the key (the correct rotor positions).
There's a slight caveat in what I just said: Obtaining a real Enigma machine from a sinking submarine was indeed a crucial part in the cryptanalysis of Enigma in WW2. It allowed the British to build an electromechanical device known as "Bombe" (designed by Alan Turing), which ultimately could be used to decipher some (not all) Enigma messages (greatly aiding the allies in the war). It should also be noted that many of the advances of the British in breaking the Enigma were based on knowledge shared with them by Polish cryptanalysts (Marian Rejewski among them) who had began work on Enigma at a much earlier time and had had some breakthroughs. Their outstanding work shouldn't be forgotten.
Still, breaking Enigma took years of work by some of the world's most talented cryptanalysts at the time! So I don't think I'd stand a chance.
Especially because Alan Turing et al. had tons of encrypted Enigma messages to work with (hundreds every day). While I only have two very short ones. In general, the shorter the encrypted message, the harder it is to decrypt (because statistical approaches only become powerful for long messages).
Addendum:
For anyone who loves cryptography, this one is actually solvable (it's relatively easy). I'll give you some hints to guide you:
- It's a substitution cipher
- It uses a keyword
- The keyword is short, so look out for repeating strings in the cipher-text
- Both the keyword and the plaintext are in English (without spelling-mistakes)
