Network Processor Module


    0.0.5 • Public • Published


    Identify the processor architecture of binary files.


    On the command line

    Simply install with npm install -g binarycpu and then call this with the path you wish to scan. e.g.

    binarycpu c:\\apps

    And it will print out the file names of identified PE/MZ binary files with their appropriate cpu architecture (see table below).

    In your own code

    const binarycpu = require('binarycpu')
    const arch = binarycpu.determinePEArch(filename)

    null is returned if the file is not a MZ/PE file. If the processor architecture is unknown it will return unknown as well as the hex identifier.

    Possible architectures

    These have been kept the same as the Microsoft docs for PE files.

    • Only Portable Executable files are supported (ELF, mach-O could be added later)
    • Errors are thrown if it is a MZ file but it can't find the PE signature


    npm i binarycpu
