Skill UI

This skill provides a systematic cryptographic audit tool designed to review applications for security vulnerabilities. It scans source code and configuration files to detect weak hashing algorithms (MD5, SHA-1), insecure cipher modes (ECB), hardcoded secrets, and deprecated protocols like TLS 1.0. Essential for security assessments, compliance checks, and maintaining secure coding practices.

This playbook provides expert-level techniques for cryptanalysis of symmetric encryption. It details how to exploit weaknesses in various modes and algorithms, including CBC padding oracle attacks, ECB mode exploitation, bit flipping attacks, stream cipher key reuse, and meet-in-the-middle attacks. Essential for authorized penetration testing and CTF challenges.
