pefile

Small library and tool to list and extract resources from Portable Executable (PE) files.

Installing the tool

go get -u github.com/folbricht/pefile/cmd/pe

Running the tool

List available resources in the file:

# pe list-resources /path/to/file.exe
3/1/1033
3/2/1033
5/105/1033
5/106/1033
10/SOMERESOURCE/1033
14/103/1033

Extract a single resource to STDOUT:

# pe extract-resource /path/to/file.exe 10/SOMERESOURCE/1033

Extract a single resource to a file:

# pe extract-resource /path/to/file.exe 10/SOMERESOURCE/1033 /tmp/someresource.bin

Extract all resources to a directory, preserving the directory layout from the PE file.

# pe extract-resources /path/to/file.exe /tmp/resources

Using the library

f, err := pefile.Open("/path/to/file.exe")
if err != nil {
  return err
}
defer f.Close()
resources, err := f.GetResources()
if err != nil {
  return err
}
for _, r := range resources {
  fmt.Println("Name:", r.Name, ", Size:", len(r.Data))
}
