Opcodes in the output - Githubissues

nfreitas11 commented 6 years ago

Hello, first of all congratz on the tool. I've tried it out and I really enjoyed using it. One thing that I think may be useful is adding the opcodes between the address and the assembly instructions. Making it look like the output of objdump:

Shellen:

L:dsm:x86_32 > \xb0\x0b\x31\xc9\x51\x68\x2f\x2f\x73\x68\x68\x2f\x62\x69\x6e\x89\xe3\xcd\x80
    0x00080000: mov     al, 0xb
    0x00080002: xor     ecx, ecx
    0x00080004: push    ecx
    0x00080005: push    0x68732f2f
    0x0008000A: push    0x6e69622f
    0x0008000F: mov     ebx, esp
    0x00080011: int     0x80

Objdump:

 8048091:   b0 0b                   mov    al,0xb
 8048093:   31 c9                   xor    ecx,ecx
 8048095:   51                      push   ecx
 8048096:   68 2f 2f 73 68          push   0x68732f2f
 804809b:   68 2f 62 69 6e          push   0x6e69622f
 80480a0:   89 e3                   mov    ebx,esp
 80480a2:   cd 80                   int    0x80

For instance, it might be useful while writing Shellcode to see how many bytes took a certain instruction... What do you think?

Kind regards
