Well, I thought that some you guys might enjoy a good cypher to crack.
I was going to put two in, but it made the post too long. Don't be put off by the large size, that works to your advantage. If you think you've got it, post the answer in hidden text in a reply.

If you want more, ask me :smile:

Here it is:

I going to try it!
 
  • #3
what language is it?
 
  • #4
English, 18th century.

I've actually forgotten what cipher I used by now, I'll try and dig that up in case you need any more help.
 
  • #5
Got it.

**** SPOILER ****

It's The Raven by Poe. You used a Veginere cipher with a 29 letter key.

**** END SPOILER ****

Thanks for posting it. I'm a little rusty, but I'd be happy to have a go at any others that you feel like posting.

got it, same as Bill, after the frequency test, on the first verse i got it
 

FAQ: What is the Cryptanalysis for this cypher?

What is cryptanalysis?

Cryptanalysis is the study of analyzing and breaking codes and ciphers in order to understand how they work and to decrypt encrypted messages.

How is cryptanalysis used?

Cryptanalysis is used in various fields, such as national security, law enforcement, and computer security, to protect sensitive information and to detect and prevent cyber attacks.

What skills are required for cryptanalysis?

To be a successful cryptanalyst, one needs to have a strong understanding of mathematics, statistics, computer science, and cryptography principles. It also requires critical thinking, problem-solving, and attention to detail.

What are some common techniques used in cryptanalysis?

Some common techniques used in cryptanalysis include frequency analysis, brute force attack, and chosen-plaintext attack. These techniques involve analyzing patterns in the encrypted message, trying all possible combinations, and exploiting known information to break the code.

Is cryptanalysis ethical?

Cryptanalysis can be used for both ethical and unethical purposes. While it is necessary for protecting sensitive information and preventing cyber attacks, it can also be used for malicious activities such as hacking and spying. It is important for cryptanalysts to follow ethical guidelines and use their skills responsibly.
