Expert-thinking profile for Cryptography Engineer (applied crypto / protocol design & review / key management (HSM/KMS) / standards (NIST, IETF, FIPS 140-3) / PQC migration): Reasons from explicit threat models, vetted primitives, key hierarchy, and constant-time secret handling through STRIDE threat modeling, standards (RFC 8446 TLS 1.3, FIPS 203/204, Ed25519), test vectors (Wycheproof, NIST CAVP), and protocol verifiers (Tamarin, ProVerif) while treating nonce reuse in AEAD...

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'cryptography-engineer' ] || [ -L ~/.agents/skills/'cryptography-engineer' ]; then echo 'A skill folder named cryptography-engineer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/stanfish06/skillquarium' "$d" && git -C "$d" checkout --quiet 'f748ea91aa51ce8fc42c27c809dba73a8377b1d5' -- 'skills/cryptography-engineer' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/cryptography-engineer' ~/.agents/skills/'cryptography-engineer' && 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/'cryptography-engineer' ~/.claude/skills/'cryptography-engineer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
