The presence of sequences like123456781AAAAAAAAAAAAAAAin the dumped data suggests that our assumption regarding the padding is indeed accurate. 通过所有的拼图部分,很明显 wasm 加密遵循以下步骤: 1.使用 Base64 解码输入。 2.使用 AES-192
一,使用wasm2js这个库导出加密函数。 直接安装wasm2js这个库,github地址在这里: https://github.com/thlorenz/wasm2js 按照它提供的方法,把wasm文件转成js代码: const wasm2js = require('wasm2js'); const fs = require('fs'); const wasmBuffer = fs.readFileSync("main.wasm"); const js = wasm2j...
不慌,继续使用搜索引擎,看看有没有直接调用wasm文件的库。 通过一番搜索后,找到了pywasm这个库: http://accu.cc/content/py/pywasm/overview/ 根据它上面的示例代码,很快就写出了爬取代码: # -*- coding: utf-8 -*-importmathimportrandomimporttimeimportpywasmimportrequestsdefmain():sums=0headers={"User...
