CHX Clipboard HexDumper is a command-line tool written in Rust that allows users to read binary data of a file on disk, convert it to a hex dump or a base64 encoded string, and copy it to the clipboard. This tool is designed for developers and security experts who need to quickly transfer binary data in a readable or encoded format without manual conversion.

Works cross-platform for Windows, Linux, and MacOS.

You can either build from source, or downloads available https://github.com/0xflux/chx/releases/ - why not add it to your PATH for easy usage!

• Read binary data from specified file paths.
• Convert binary data into hex dump format.
• Optionally convert hex dump to base64 encoding.
• Copy the resulting string directly to the system clipboard.

Here you can see a base64 encoded string as an input, copied to the clipboard by chx. When reversing the base64 string in Cyber Chef, you can clearly see it is in fact a Windows binary.

For copying a direct hexdump (formatted C friendly) to your clipboard:

./chx -f /path/to/your/binary

An example of the output:

\x4d\x5a\x90\x00\x03\x00\x00\x00\x04\x00\x00...

To copy as a base64 encoded string, add the -b flag:

./chx -f /path/to/your/binary -b

An example of the output:

TVqQAAMAAAAEAAAA//8AALgAAAAAAAAA...

For help see: ./chx --help

A direct download can be found within the GitHub repo.
