Variables

var ELFStart = [4]byte{127, 69, 76, 70} // this is { 0x7f, 'E', 'L', 'F' }

Functions

func CalculateELFMetadata

func CalculateELFMetadata(reader io.Reader) (bool, string, error)

CalculateELFMetadata returns whether the file is an ELF and if so, returns its SHA256

Types

type ExecutableFile

type ExecutableFile struct {
	Digest          string       `json:"digest"` // the file's SHA256
	Path            string       `json:"path"`
	Size            uint64       `json:"size"`
	Category        FileCategory `json:"file_category"`
	InSquashedImage bool         `json:"in_squashed_image"`
}

type FileCategory

type FileCategory string

const (
	// CategoryElf is a linux executable
	CategoryElf FileCategory = "ELF"
)
