Helps Claude Code understand Sui blockchain keypair and cryptography operations, providing guidelines and examples for key generation, signing, verification, address derivation, and multi-signature scheme support. Use when working with cryptography in Sui development or when the user mentions keypairs, cryptography, signing, or verification.
Use this skill when implementing encryption, hashing, TLS configuration, JWT tokens, or key management. Triggers on encryption, hashing, bcrypt, AES, RSA, TLS certificates, JWT signing, HMAC, key rotation, digital signatures, and any task requiring cryptographic implementation or protocol selection.
Comprehensive cryptography guidance covering encryption algorithms, password hashing, TLS configuration, key management, and post-quantum considerations. Use when implementing encryption, choosing hashing algorithms, configuring TLS/SSL, managing cryptographic keys, or reviewing cryptographic implementations.
Applies multi-algorithm cryptography (ED25519, P-256, RSA-4096) using Sorcha.Cryptography. Use when: implementing signing, verification, encryption, key generation, HD wallets, or address encoding.
Automatically discover cryptography skills when working with encryption, TLS, certificates, PKI, and security
Zero-knowledge cryptography and privacy patterns on Stellar/Soroban. Covers Groth16 verification, BLS12-381 (CAP-0059, available), BN254 + Poseidon host functions (CAP-0074/0075, status-sensitive), Noir / RISC Zero integration, privacy pools, confidential tokens, Merkle tree commitments, and status-sensitive guidance for protocol/SDK readiness. Use when building privacy-preserving applications or ZK-verifier contracts on Stellar.
Cryptography techniques for CTF challenges. Use when attacking encryption, hashing, ZKP, signatures, or mathematical crypto problems.
Cryptography expert for TLS, symmetric/asymmetric encryption, hashing, and key management
Master blockchain fundamentals including consensus, cryptography, and distributed systems
Solve CTF cryptography challenges by identifying, analyzing, and exploiting weak crypto implementations in binaries to extract keys or decrypt data. Use for custom ciphers, weak crypto, key extraction, or algorithm identification.
Cryptography tools for RSA attacks, classical ciphers, XOR analysis, and frequency analysis in CTF challenges. Trigger: When solving crypto challenges, RSA, XOR, Caesar, or Vigenere ciphers.
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.
