80 / 100 · Low risk

Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Cryptographic patterns for encryption, hashing, key derivation functions (KDFs), TLS configuration, JWT signing, password storage, and authentication tokens — with deterministic weak-algorithm detection script. Identifies use of deprecated algorithms (MD5, SHA1, DES, ECB mode) and insecure configurations. Use proactively when reviewing code that uses encryption, hashing, or key management, auditing password storage or authentication tokens, checking TLS configuration, reviewing JWT signing algo…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'crypto-patterns' ] || [ -L ~/.agents/skills/'crypto-patterns' ]; then echo 'A skill folder named crypto-patterns already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Everyone-Needs-A-Copilot/claude-copilot' "$d" && git -C "$d" checkout --quiet '0f57aa588a5c2c7da021b976edc1b176ea602022' -- '.claude/skills/security/crypto-patterns' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/security/crypto-patterns' ~/.agents/skills/'crypto-patterns' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'crypto-patterns' ~/.claude/skills/'crypto-patterns' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
