# Pentest CTF Crypto ## Purpose Analyze and break cryptographic implementations, including classical ciphers, RSA weak keys, and hash extensions. ## Core Workflow 1. **Cipher Identification**: Identify the type of encryption or encoding used (e.g., Base64, Caesar, RSA). 2. **Classical Cracking**: Brute-force or analyze frequency for classical ciphers using `ciphey` or online tools. 3. **RSA Attacks**: Check for common RSA weaknesses (small e, small factors) using `RsaCtfTool`. 4. **Hash Analysis**: Identify hash types and attempt cracking or length extension attacks using `hashcat` or `hashpump`. 5. **Math/Primes**: Solve mathematical problems related to cryptography using `sagemath`. ## References - `references/tools.md` - `references/workflows.md`
