🤔 What is this?

Ciphey is an automated decryption tool. Input encrypted text, get the decrypted text back.

"What type of encryption?"

That's the point. You don't know, you just know it's possibly encrypted. Ciphey will figure it out for you.

Ciphey can solve most things in 3 seconds or less.

Ciphey demo

The technical part. Ciphey uses a custom built artifical intelligence module (AuSearch) with a Cipher Detection Interface to approximate what something is encrypted with. And then a custom-built, customisable natural languge processing Language Checker Interface, which can detect when the given text becomes plaintext.

And that's just the tip of the iceberg. For the full technical explanation, check out our documentation.

✨ Features

  • 20+ encryptions supported such as encodings (binary, base64) and normal encryptions like Caesar cipher, Transposition and more. For the full list, click here
  • Custom Built Artificial Intelligence with Augmented Search (AuSearch) for answering the question "what encryption was used?" Resulting in decryptions taking less than 3 seconds.
  • Custom built natural language processing module Ciphey can determine whether something is plaintext or not. It has an incredibly high accuracy, along with being fast.
  • Multi Language Support at present, only German & English (with AU, UK, CAN, USA variants).
  • Supports encryptions Which the alternatives such as CyberChef Magic do not.
  • C++ core Blazingly fast.

🔭 Ciphey vs CyberChef

🔁 Base64 Encoded 42 times

Name ⚡ Ciphey ⚡ 🐢 CyberChef 🐢
Gif The guy she tells you not to worry about You
Time 2 seconds 6 seconds
Setup
  • Run ciphey on the file
  • Set the regex param to "{"
  • You need to know how many times to recurse
  • You need to know it's Base64 all the way down
  • You need to load CyberChef (it's a bloated JS app)
  • Know enough about CyberChef to create this pipeline
  • Invert the match

Note The gifs may load at different times, so one may appear significantly faster than another.
A note on magic CyberChef's most similar feature to Ciphey is Magic. Magic fails instantly on this input and crashes. The only way we could force CyberChef to compete was to manually define it.

We also tested CyberChef and Ciphey with a 6gb file. Ciphey cracked it in 5 minutes and 54 seconds. CyberChef crashed before it even started.

To get rid of the progress bars, probability table, and all the noise use the quiet mode.

ciphey -t "encrypted text here" -q

For a full list of arguments, run ciphey --help.

🎪 Contributors

Ciphey was invented by Brandon Skerritt in 2008, and revived in 2019. Ciphey wouldn't be where it was today without Cyclic3 - president of UoL's Cyber Security Society.

Ciphey was revived & recreated by the Cyber Security Society for use in CTFs. If you're ever in Liverpool, consider giving a talk or sponsoring our events. Email us at cybersecurity@society.liverpoolguild.org to find out more 🤠

Major Credit to George H for working out how we could use proper algorithms to speed up the search process. Special thanks to varghalladesign for designing the logo. Check out their other design work!
