Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
6 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by Netw0rkNoob on GitHub. Read the source before you install it.

Installation

Install the Ctf Crypto AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Netw0rkNoob/VulnClaw.git /tmp/VulnClaw
mkdir -p .claude/skills
cp -r /tmp/VulnClaw/vulnclaw/skills/specialized/ctf-crypto .claude/skills/ctf-crypto

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Ctf Crypto in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Ctf Crypto on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Ctf Crypto is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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）
ctf-crypto → 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

Frequently asked questions

What does the Ctf Crypto AI skill do?

Why use Ctf Crypto on TypingMind?

Because you install it once and use it with any model. Ctf Crypto is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Ctf Crypto in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Netw0rkNoob/VulnClaw/tree/main/vulnclaw/skills/specialized/ctf-crypto. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Ctf Crypto?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Ctf Crypto?

As many as you like. As long as a model supports skills, you can use Ctf Crypto with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Ctf Crypto AI skill free?

Yes. It is published on GitHub by Netw0rkNoob under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
