PASM is a simple, multi-purpose assembler and disassembler for Linux. It leverages from Rasm2 functionalities and wraps them into a colorful, user-friendly CLI. Extremely useful during shellcode development and heavy Assembly coding.
Go to the cloned repository and run setup.py:
$ python3 setup.py install
It will install all needed dependencies.
WARNING: If you have different package manager than apt-get, you will have to install radare2 manually.
Then launch PASM from your terminal:
$ python3 pasm.py
- Support for over 40 architectures
- Easily configurable
- Clear minimalistic output
- Power and versatility of Rasm2 wrapped into custom interface
- Null-bytes and bad characters warning
In order to switch between assembly and disassembly modes, simply run asm or disasm command. Then enter the instructions or opcodes you want to assembly (or disassembly):
asm:[x86][32][linux][little][att]
-➤ disasm
[+] Changed mode to disasm
disasm:[x86][32][linux][little][att]
-➤ 9090c3
[+] Disassembly of '9090c3 ':
0x00000000 1 90 nop
0x00000001 1 90 nop
0x00000002 1 c3 retl
disasm:[x86][32][linux][little][att]
-➤ \x90\x90\xc3
[+] Disassembly of '\x90\x90\xc3 ':
0x00000000 1 90 nop
0x00000001 1 90 nop
0x00000002 1 c3 retl
The prompt of PASM is divided into 5 differrent sections:
mode:[architecture][number_of_bits][os][endianess][assembly_syntax]
->
Each section presents us with current assembler option. Every option can be changed from the CLI:
asm:[x86][32][linux][little][att]
-> os linux
[+] Changed OS to linux
To change default settings of PASM (used at startup), editconfig.ini:
[assembler]
bits = 32
endian = little
os = linux
syntax = att
arch = x86
starting_mode = asm
