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.
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.
- 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.

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.

There are 3 ways to run Ciphey.
- File Input
ciphey - encrypted.txt - Unqualified input
ciphey -- "Encrypted input" - Normal way
ciphey -t "Encrypted input"
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.
You can import Ciphey's main and use it in your own programs and code. from Ciphey.__main__ import main
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 [email protected] 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!
