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.
