Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

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
- 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
- 工具验证 — 使用
python_execute执行攻击代码，用crypto_decode做辅助编解码 - 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）。
