- Go (Golang): Installation instructions: https://golang.org/doc/install
- NASM (Netwide Assembler): sudo apt-get install nasm
This creates our reference executable so we can explore a binary file that is properly structured.
To compile and run:
nasm -f elf64 -o min.o min.asm
ld -o min_asm min.o
./min_asm
This Go program creates a minimal ELF file. It will only create the parts were absolutely necessary to run a executable:
- ELF header
- Program header
- Instructions/Data
To run:
go run min.go
chmod +x minimal_elf
./minimal_elf
This is creates an (almost) valid elf file by copying the structure from the min.asm nasm output. Therefore it will work with most utilities like objdump or readelf.
To run:
go run valid_elf.go
This will overwrite minimal_elf.
- objdump
- readelf
- vbindiff
This project is for educational purposes only. The created ELF files are minimal examples and should not be used as templates for production executables.
