/BytesCode-class

BytesCode is a class with a to_opcode(file) method this method return instruction asm in opcode

Primary LanguageRuby

Instruction Assembly to Opcode- Library

Getting Started

gem install BytesCode

    require 'BytesCode'

Convert Instruction asm to Opcode

    BytesCode.to_opcode("executable")

###Delete bad chars with countdown

BytesCode.to_opcode("executable", countdown=true) #by default is false

or

BytesCode.countdown('\xeb\x1e\x5e\x48\x31\xc0\xb0\x01\x48\x89\xc7\x48\x89\xfa\x48\x83\xc2\x0e\x0f\x05\x48\x31\xc0\x48\x83\xc0\x3c\x48\x31\xff\x0f\x05\xe8\xdd\xff\xff\xff\x48\x65\x6c\x6c\x6f\x2c\x20\x77\x6f\x72\x6c\x64\x21\x0a')

#output => \xeb\x1e\x5e\x48\x31\xc0\xb0\x01\x48\x89\xc7\x48\x89\xfa\x48\x83\xc2\x0e\x0f\x05\x48\x31\xc0\x48\x83\xc0\x3c\x48\x31\x0f\x05\xe8\xdd\x48\x65\x6c\x6c\x6f\x2c\x20\x77\x6f\x72\x6c\x64\x21

##Binary test

global _start

_start:
    jmp short string


code:
    pop rsi
    xor rax, rax
    mov al, 1
    mov rdi, rax
    mov rdx, rdi
    add rdx, 14
    syscall

    xor rax, rax
    add rax, 60
    xor rdi, rdi
    syscall

string:
    call code
    db 'Hello, world!', 0x0A
