Online Assembler and Disassembler.
This project ported capstone and keystone into the browser via emscripten.
Playground: https://disasm.czbix.com/ (support offline usage)
There are two packages available: capstone-wasm and keystone-wasm.
import {
Const, Capstone, loadCapstone,
} from 'capstone-wasm'
await loadCapstone()
const capstone = new Capstone(Const.CS_ARCH_X86, Const.CS_MODE_32)
// the code can be bytes array or Uint8Array
const code = [0x55, 0x8b, 0xec, 0x83, 0xc4, 0x0c, 0xc3]
const insns = capstone.disasm(code, {
address: 0x1000,
})
insns.forEach(insn => {
console.log(insn.mnemonic, insn.opStr)
})import {
Const, Keystone, loadKeystone,
} from 'keystone-wasm'
await loadKeystone()
const capstone = new Keystone(Const.KS_ARCH_X86, Const.KS_MODE_32)
// can separate code by `\n` or `;`
const code = `push ebp
mov ebp, esp
add esp, 0xc
ret`
// bytes is a Uint8Array
const bytes = keystone.asm(code, {
address: 0x1000,
})Not support detail feature(CS_OPT_DETAIL) yet.
