Assistance Cracking Classical Cipher @Nick, the explanation is right above. Attacking a Vigenere cipher with known key length is trivial. Let me repeat. You feed the cipher with various keys of that length and count digrams in decrypted gibberish until you hit some threshold. At this point there would be few partially colliding keys that would partially decrypt the message. Look at these, reconstruct the rest of the message and roll it back to the original key if you must. |

Assistance Cracking Classical Cipher There is also a word: a curious mind that truly willing to lean may use the answer to reconstruct a solution. Here, having all the details, the rest is quite straightforward. Feed the cipher with 6-char keys and count digrams until some threshold. Then simply reconstruct the rest of decrypted text that still corrupted. |
