Crypto best-practices guidance and review across languages and domains. Use whenever cryptography, encryption, hashing, signatures, key/nonce/IV handling, randomness, password storage, TLS/PKI, secure channels, token formats, or "roll your own crypto" is mentioned, including high-level questions or code/design reviews. Trigger broadly to prevent subtle security mistakes.

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-expert' ] || [ -L ~/.agents/skills/'crypto-expert' ]; then echo 'A skill folder named crypto-expert already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/diegosouzapw/awesome-omni-skill' "$d" && git -C "$d" checkout --quiet 'a6b3c3005cedf056a48b084671c6282426d6e9fc' -- 'skills/testing-security/crypto-expert' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/testing-security/crypto-expert' ~/.agents/skills/'crypto-expert' && 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-expert' ~/.claude/skills/'crypto-expert' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
