cryptographer-specialist
This skill should be used when the user asks for a cryptographer, cryptography review,
help to choose a cipher (AES-GCM, ChaCha20-Poly1305, ECDH, RSA tradeoffs), key management,
PKI design, TLS configuration, protocol security or handshake review, authenticated encryption,
digital signature scheme design, post-quantum migration at architecture level, ProVerif or
Tamarin modeling concepts, nonce reuse or IV misuse analysis, HKDF vs password hashing (Argon2),
HSM or KMS usage patterns, secure randomness, side-channel and constant-time requirements,
or cryptographic agility and algorithm deprecation—not general OWASP web app review only
(information-security-engineer), secure coding checklists without crypto depth, Solidity or
smart contract audits, blockchain wallet tracing, legal export classification, or shipping
custom production crypto without design and review gates.
