Master blockchain fundamentals including consensus, cryptography, and distributed systems
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.
Audit cryptography implementation — algorithm choice, key sizes, KDF parameters, IV/nonce handling, signature verification, randomness, TLS configuration, and key rotation. Deeper than owasp-audit A02. Use when the user mentions 'crypto review,' 'cryptography audit,' 'encryption review,' 'KDF,' 'PBKDF2,' 'Argon2,' 'bcrypt cost,' 'IV reuse,' 'nonce reuse,' 'AES mode,' 'AES-GCM,' 'AES-ECB,' 'signature verification,' 'TLS configuration,' 'cipher suites,' 'key rotation,' 'libsodium,' 'BoringSSL,' or 'is this crypto right.'
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.
Audit application source code and configuration for cryptography and secrets hygiene issues: hardcoded API keys, committed .env files, private keys, weak hashes, insecure encryption modes, unsafe randomness, bad KDF/password hashing, JWT signing mistakes, disabled TLS verification, and dangerous serialization. Runs a dependency-free offline scanner for high-recall findings, then the model confirms impact and writes concrete fixes with redacted evidence. Use when reviewing app code that handles encryption, tokens, sessions, certificates, or credentials; when asked to scan for hardcoded secrets, exposed API keys, weak crypto, AES-ECB/CBC misuse, MD5/SHA1 password hashing, insecure random tokens, verify=False, InsecureSkipVerify, rejectUnauthorized false, alg none JWTs, or committed private keys. Not for Terraform/Kubernetes-only audits (use infra-security), package install-hook risk (use supply-chain-security), or vetting an agent skill before install (use skill-security).
Security best practices and vulnerability prevention for Golang. Covers injection (SQL, command, XSS), cryptography, filesystem safety, network security, cookies, secrets management, memory safety, and logging. Apply when writing, reviewing, or auditing Go code for security, or when working on any risky code involving crypto, I/O, secrets management, user input handling, or authentication. Includes configuration of security tools.
Security code review for vulnerabilities. Use when asked to "security review", "find vulnerabilities", "check for security issues", "audit security", "OWASP review", or review code for injection, XSS, authentication, authorization, cryptography issues. Provides systematic review with confidence-based reporting.
AI-powered codebase security scanner that reasons about code like a security researcher — tracing data flows, understanding component interactions, and catching vulnerabilities that pattern-matching tools miss. Use this skill when asked to scan code for security vulnerabilities, find bugs, check for SQL injection, XSS, command injection, exposed API keys, hardcoded secrets, insecure dependencies, access control issues, or any request like "is my code secure?", "review for security issues", "audit this codebase", or "check for vulnerabilities". Covers injection flaws, authentication and access control bugs, secrets exposure, weak cryptography, insecure dependencies, and business logic issues across JavaScript, TypeScript, Python, Java, PHP, Go, Ruby, and Rust.
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.
Analyze Flutter and mobile applications for OWASP Mobile Top 10 (2024) security compliance. Use this skill when performing security audits, vulnerability assessments, or compliance checks on mobile applications. Performs automated scans for hardcoded secrets, insecure storage, weak cryptography, network security issues, and provides detailed remediation guidance.
Elite Application Security engineer specializing in secure SDLC, OWASP Top 10 2025, SAST/DAST/SCA integration, threat modeling (STRIDE), and vulnerability remediation. Expert in security testing, cryptography, authentication patterns, and DevSecOps automation. Use when securing applications, implementing security controls, or conducting security assessments.
Comprehensive security guide for Capacitor apps using Capsec scanner. Covers 63+ security rules across secrets, storage, network, authentication, cryptography, and platform-specific vulnerabilities. Use this skill when users need to secure their mobile app or run security audits.
