How do ciphers change plaintext into numeric digits for computing? @CodesInChaos: Thanks! I didn't know. I will research this and update my answer or delete the answer. |

Making a cipher (ex: Vigenere) harder to break @B-Con: Ahh, I see. So 2^(4.7) = 26. How would one actually do this? I am not sure that I understand. |

Making a cipher (ex: Vigenere) harder to break @CodesInChaos: Thanks for the comment. I don't want to use this for anything serious, I am just learning. I would like to understand how one might combine the Vigenere with something simple. Something that would be easy to understand and to implement. What do you mean by the 4.7 bit one? |

Are there hash algorithms with variable length output? Thanks for the answer. Since you asked: The reason for my questions wasn't deep at all. I had thought about padding of keys/passwords, and was thinking that instead of padding key, one could just generate a hash of a specific length of a key. Thereby all key lengths should be "allowed", but I don't know if this is secure. I will probably ask a question about this later after I have thought more about it. |

Assistance Cracking Classical Cipher Eli, I would have to agree with Hendrik. Of course one can find the key from your solution, but that doesn't help the OP learn how to actually find the key in future problems. |
