# 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 ## 场景路由 | 场景 | 参考文档 | 核心攻击 | |------|---------|---------| | RSA 攻击 | `rsa-attacks-cheatsheet.md` | 小e/共模/Wiener/Pollard/Fermat/Coppersmith | | AES/分组密码攻击 | `aes-and-block-cipher-attacks.md` | ECB翻转/Padding Oracle/GCM nonce重用 | | ECC 攻击 | `ecc-attacks-cheatsheet.md` | 小子群/invalid curve/Smart/Pohlig-Hellman | | PRNG/流密码攻击 | `prng-and-stream-cipher-attacks.md` | MT19937/LCG/LFSR/RC4 | | 古典密码 | `classic-cipher-attacks.md` | Vigenere/XOR频率分析/OTP重用 | | 格攻击 | `lattice-and-lwe-attacks.md` | LLL/BKZ/HNP/LWE embedding | ## 快速判题指南 | 题目特征 | 可能攻击 | 推荐参考 | |---------|---------|---------| | 给了 n, e, c | RSA | rsa-attacks-cheatsheet.md | | e=3 或 e 很小 | RSA 小指数攻击 | rsa-attacks-cheatsheet.md | | 多组 (n, e, c) 且 n 相同 | RSA 共模攻击 | rsa-attacks-cheatsheet.md | | n 很大但 e 很大 | Wiener 攻击 | rsa-attacks-cheatsheet.md | | AES-CBC + 解密 oracle | Padding Oracle | aes-and-block-cipher-attacks.md | | AES-ECB + 可控明文 | ECB 字节翻转 | aes-and-block-cipher-attacks.md | | 椭圆曲线参数 | ECC 攻击 | ecc-attacks-cheatsheet.md | | 给了随机数序列 | PRNG 预测 | prng-and-stream-cipher-attacks.md | | 给了密文和部分明文 | XOR/流密码 | classic-cipher-attacks.md | | 矩阵/向量运算 | 格攻击 | lattice-and-lwe-attacks.md | ## 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`)。 ## 來源與維護 - 原始 skill 已保存於 `references/upstream-skill.md`;README/LICENSE 已保存於 `references/`。
