slack-asm

A Slack bot written in pure x86_64 Linux assembly, no C, no Rust, no libc.

Overview

A slack bot written in pure x86_64 assembly!

Features

(These are only the currently implemented ones, see the roadmap for the full plan)

• Linux syscalls for networking (socket, connect, sendto, recvfrom).
• TLS 1.2 record layer and handshake (ClientHello → ServerHello + Cert + ServerHelloDone).
• SHA-256 and HMAC-SHA256 (all test vectors pass).
• Probably Something else, lets be honest im only reupdating this list when its convenient for me.

Cool Things

• The comments tell you less info than the code.
• It probably has security issues, but they are not documented anywhere, so its fine!
• The code is not actually that bad, if you squint.

Why

Because it seemed like a good idea at the time.
Now im doing it for Stardance.

Building

Requires:

• make
• nasm
• ld (GNU ld)
• Linux x86_64

$ make

Target

• OS: Linux (x86_64)
• Syscall ABI: syscall instruction, kernel calling convention
• Calling convention: System V AMD64 (for any interop, though there shouldn't be any)

Running the bot

Use the docker compose file..

Running the code without docker

Run run.sh script or do ./slack directly.
