๐Ÿค” What is this?

Input encrypted text, get the decrypted text back.

โ€œWhat type of encryption?โ€

Thatโ€™s the point. You donโ€™t know, you just know itโ€™s possibly encrypted. Ciphey will figure it out for you.

Ciphey can solve most things in 3 seconds or less.

Ciphey demo

Ciphey aims to be a tool to automate a lot of decryptions & decodings such as multiple base encodings, classical ciphers, hashes or more advanced cryptography.

If you donโ€™t know much about cryptography, or you want to quickly check the ciphertext before working on it yourself, Ciphey is for you.

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

No neural networks or bloated AI here. We only use what is fast and minimal.

And thatโ€™s just the tip of the iceberg. For the full technical explanation, check out our documentation.

โœจ Features

  • 50+ encryptions/encodings supported such as binary, Morse code and Base64. Classical ciphers like the Caesar cipher, Affine cipher and the Vigenere cipher. Along with modern encryption like repeating-key XOR and more. For the full list, click here
  • Custom Built Artificial Intelligence with Augmented Search (AuSearch) for answering the question โ€œwhat encryption was used?โ€ Resulting in decryptions taking less than 3 seconds.
  • Custom built natural language processing module Ciphey can determine whether something is plaintext or not. Whether that plaintext is JSON, a CTF flag, or English, Ciphey can get it in a couple of milliseconds.
  • Multi Language Support at present, only German & English (with AU, UK, CAN, USA variants).
  • Supports encryptions and hashes Which the alternatives such as CyberChef Magic do not.
  • C++ core Blazingly fast.

๐Ÿ”ญ Ciphey vs CyberChef

๐Ÿ” Base64 Encoded 42 times

Name โšก Ciphey โšก ๐Ÿข CyberChef ๐Ÿข
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 CyberChefโ€™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.

๐Ÿƒโ€โ™€๏ธRunning Ciphey

There are 3 ways to run Ciphey.

  1. File Input ciphey -f encrypted.txt
  2. Unqualified input ciphey -- "Encrypted input"
  3. Normal way ciphey -t "Encrypted input"

Gif showing 3 ways to run Ciphey

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.

โš—๏ธ Importing Ciphey

You can import Cipheyโ€™s main and use it in your own programs and code. from Ciphey.__main__ import main

๐ŸŽช Contributors

Ciphey was invented by Bee in 2008, and revived in 2019. Ciphey wouldnโ€™t be where it was today without Cyclic3 - president of UoLโ€™s Cyber Security Society.

Ciphey was revived & recreated by the Cyber Security Society for use in CTFs. If youโ€™re ever in Liverpool, consider giving a talk or sponsoring our events. Email us at [email protected] to find out more ๐Ÿค 

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!
