About this skill

Cryptography tools for solving CTF challenges involving ciphers, hashing, and weak encryption.

What this skill tells your AI

The instructions your AI receives, as published by jd-opensource/joysafeter in skills/pentest-ctf-crypto/SKILL.md and read by Ahel’s review.

Analyze and break cryptographic implementations, including classical ciphers, RSA weak keys, and hash extensions.

Cipher Identification: Identify the type of encryption or encoding used (e.g., Base64, Caesar, RSA).
Classical Cracking: Brute-force or analyze frequency for classical ciphers using ciphey or online tools.
RSA Attacks: Check for common RSA weaknesses (small e, small factors) using RsaCtfTool.
Hash Analysis: Identify hash types and attempt cracking or length extension attacks using hashcat or hashpump.
Math/Primes: Solve mathematical problems related to cryptography using sagemath.
