CTF 密码学攻击知识库

针对 CTF Crypto 题目的实战攻击知识库,提供具体攻击参数、数学公式、Python 代码片段。

与 -crypto-toolkit 的区别:

  • -crypto-toolkit → 编解码操作工具(base64 解码、MD5 哈希、AES 加解密)
  • crypto-ctf-attacks → 密码学攻击知识(RSA 小指数攻击怎么做、Padding Oracle 怎么利用)

核心原则

  1. 先识别加密体系 — 看密钥长度、加密模式、已知量,确定攻击方向
  2. 工具验证 — 使用 python_execute 执行攻击代码,用 crypto_decode 做辅助编解码
  3. 参数敏感 — 密码学攻击对参数极其敏感,必须精确计算

Hermes 使用適配

  • 來源為 專案技能,已匯入 Hermes 本地 skill。僅在已授權滲透測試、CTF、內部安全評估或防禦驗證範圍內使用。
  • 原文若提到 fetch,在 Hermes 中優先使用 web_extract、browser 或 terminal(curl/HTTPie) 取得真實回應。
  • 原文若提到 python_execute,在 Hermes 中使用 execute_code 或 terminal(python3 ...);計算、編碼、hash、PoC 驗證必須用工具實測,不靠猜。
  • 原文若提到 MCP/Burp/adb/frida/jadx/chrome_devtools 等外部工具:先確認本機是否安裝或可用;不可用時以 Hermes 現有 web、browser、terminal、file、vision 工具替代,並明確標註限制。
  • 下一次滲透任務中,先載入 -pentest-flow 做總路由,再依場景載入本系列專項 skill(例如 -web-security-advanced、-osint-recon、-rapid-checklist)。

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
