Yes! Just drag your file over the input box and drop it.
can handle files up to around 500MB (depending on your browser),
however some of the operations may take a very long time to run over
this much data.
If the output is larger than a certain threshold
(default 1MiB), it will be presented to you as a file available for
download. Slices of the file can be viewed in the output if you need to
Maybe you have 10 timestamps that you want to parse or 16 encoded strings that all have the same key.
'Fork' operation (found in the 'Flow control' category) splits up the
input line by line and runs all subsequent operations on each line
separately. Each output is then displayed on a separate line. These
delimiters can be changed, so if your inputs are separated by commas,
you can change the split delimiter to a comma instead.
simple, intuitive web app for analysing and decoding data without
having to deal with complex tools or programming languages. CyberChef
encourages both technical and non-technical people to explore data
formats, encryption and compression.
data comes in all shapes, sizes and formats in the modern world –
CyberChef helps to make sense of this data all on one easy-to-use
The interface is
designed with simplicity at its heart. Complex techniques are now as
trivial as drag-and-drop. Simple functions can be combined to build up a
"recipe", potentially resulting in complex analysis, which can be
shared with other users and used with their input.
comfortable writing code, CyberChef is a quick and efficient way to
prototype solutions to a problem which can then be scripted once proven
It is expected that
CyberChef will be useful for cybersecurity and antivirus companies. It
should also appeal to the academic world and any individuals or
companies involved in the analysis of digital data, be that software
developers, analysts, mathematicians or casual puzzle solvers.
It is hoped that by releasing CyberChef through GitHub, contributions can be added which can be rolled out into future versions of the tool.
are around 200 useful operations in CyberChef for anyone working on
anything vaguely Internet-related, whether you just want to convert a
timestamp to a different format, decompress gzipped data, create a SHA3
hash, or parse an X.509 certificate to find out who issued it.
It’s the Cyber Swiss Army Knife.
