kcshell 0.0.4

How to install it:

pip3 install kcshell

OR (assuming you have Keystone and Capstone build toolchains installed)

git clone https://github.com/fdiskyou/kcshell
cd kcshell
python setup.py install

Usage

By default ‘kcshell’ starts in ‘assembler’ mode (x86 32 bits). You can change modes with ‘setmode’, and you can also change the default architecture for both the ‘assembler’ and ‘disassembler’ with ‘setarch’.

$ kcshell
-=[ kcshell v0.0.3 ]=-
Default Assembler architecture is x86 (32 bits)
asm> lsmodes
disasm, asm
asm> setmode disasm
Default Disassembler architecture is x86 (32 bits)
disasm> lsarchs
x86, mips32, arm_t, x64, arm, x16, arm64, mips64
disasm> setarch x64
Disassembler architecture is now x64
disasm>

To assemble instructions just type the instructions in the command line.

asm> jmp esp
"\xff\xe4"
asm> xor eax, eax
"\x31\xc0"
asm> setarch x64
Assembler architecture is now x64
asm> inc rax
"\x48\xff\xc0"
asm>

To go from opcodes to instructions just type them in the command line.

disasm> \xff\xe4
0x00400000:     jmp     esp
disasm> \x31\xc0
0x00400000:     xor     eax, eax
disasm> setarch x64
Disassembler architecture is now x64
disasm> \x48\xff\xc0
0x00400000:     inc     rax
disasm>

For help just use ‘?’ or ‘help <command>’.

asm> ?

Documented commands (type help <topic>):
========================================
EOF  exit  help  lsarchs  lsmodes  quit  setarch  setmode

asm> setmode disasm
Default Disassembler architecture is x86 (32 bits)
disasm> ?

Documented commands (type help <topic>):

To list all the supported architectures just go to the desired mode and use ‘lsarchs’.

asm> lsarchs
mips64, sparc64, sparc, arm_t, x64, x16, arm64, hexagon, systemz, mips32, ppc64, x86, arm, ppc32

asm> setmode disasm
Default Disassembler architecture is x86 (32 bits)
disasm> lsarchs
