What is RSA CTF Solver?
The RSA CTF Solver is a specialized security tool designed for Openclaw Skills practitioners to tackle complex cryptography challenges in competitive environments. It integrates high-performance big-integer arithmetic and number theory functions to automate the decryption of RSA ciphertexts.
This utility acts as a comprehensive engine for modular exponentiation vulnerabilities, supporting everything from simple factorization via online databases to advanced attacks like Wiener's or Common Modulus. It provides a unified command-line interface to streamline the workflow of analyzing, attacking, and retrieving plaintexts from vulnerable RSA implementations.
RSA CTF Solver Use Cases
- Solving RSA-based cryptography challenges in CTF competitions.
- Factoring large integers (n) using integrated factordb lookups.
- Decrypting ciphertexts when specific parameters like e, d, or dp are leaked.
- Automating attacks on weak RSA implementations, such as small public exponents or repeated moduli.
How RSA CTF Solver Works
- Identify Vulnerability: Analyze the given parameters (n, e, c, etc.) to match them against known RSA attack vectors.
- Parameter Preparation: Input the collected values into the standardized rsa_solver script.
- Execution: The tool runs the selected mathematical attack using gmpy2 for optimized performance.
- Result Extraction: The solver outputs the decrypted plaintext (attempting UTF-8 first) or intermediate keys like p, q, and d.
RSA CTF Solver Setup
Ensure you have Python installed, then install the required cryptographic and mathematical libraries:
pip install gmpy2>=2.1.0 sympy>=1.10.0 requests>=2.28.0
RSA CTF Solver Data Schema & Taxonomy
The skill utilizes a structured approach to inputs and outputs to ensure compatibility across different Openclaw Skills workflows:
| Data Type | Description |
|---|---|
| Input Parameters | Accepts large integers for n, e, c, p, q, d, and dp via CLI flags. |
| Attack Types | Classified by scenario (e.g., small_e, wiener, crt, rabin). |
| Output Formats | Prioritizes UTF-8 strings, falling back to Hex or BigInt for raw data. |
| External API | Optional integration with factordb for cloud-based modulus factorization. |
RSA CTF Solver Advanced Features
- Multi-vector support: Includes 11 distinct attack algorithms covering the majority of CTF scenarios.
- Automated Data Cleaning: Automatically strips whitespace and newlines from large integer inputs to prevent formatting errors.
- High-Performance Computing: Leverages gmpy2 for rapid big-integer calculations.
- Flexible Decoding: Smart detection for output formats, handling both readable text and raw binary data.
- Comprehensive Reference Guide: Includes detailed attack logic documentation for educational use within Openclaw Skills.
