name: pentest-ctf-crypto description: Cryptography tools for solving CTF challenges involving ciphers, hashing, and weak encryption.

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.
