Create and sign JSON Web Tokens (JWTs) for testing and development. Use when the user wants to generate, create, build, or sign a JWT — e.g. "create a JWT", "generate a test token", "sign this payload", "make a JWT with these claims", "build an access token". Supports HMAC, RSA, and ECDSA algorithms.
API authentication and JWT abuse playbook. Use when testing bearer tokens, API keys, claim trust, header spoofing, rate limits, and API auth boundary weaknesses.
Verify and validate JSON Web Tokens (JWTs) by checking signatures, expiration, claims, and structure. Use when the user wants to verify, validate, or check a JWT — e.g. "verify this token", "is this JWT valid", "check the signature", "validate this token against my JWKS", "is this token expired". Supports HMAC, RSA, and ECDSA with secrets, PEM keys, or JWKS endpoints.
Decode and inspect JSON Web Tokens (JWTs) without verification. Use when the user provides a JWT string and wants to see its header, payload, or claims — e.g. "decode this JWT", "what's in this token", "inspect this JWT", "show me the claims", "parse this token". Also triggers on raw JWT strings (three base64url segments separated by dots).
Assessing JSON Web Token implementations for cryptographic weaknesses, algorithm confusion attacks, and authorization bypass vulnerabilities during security engagements.
Design and implement authentication and authorization systems. Use when setting up user login, JWT tokens, OAuth, session management, or role-based access control. Handles password security, token management, SSO integration.
Build Python APIs with FastAPI, Pydantic v2, and SQLAlchemy 2.0 async. Covers project structure, JWT auth, validation, and database integration with uv package manager. Prevents 7 documented errors. Use when: creating Python APIs, implementing JWT auth, or troubleshooting 422 validation, CORS, async blocking, form data, background tasks, or OpenAPI schema errors.
Use this skill when integrating a third-party auth provider (Clerk, Auth0, WorkOS, Kinde, Stytch) with InsForge for authentication and RLS. Covers JWT configuration, client setup, database RLS policies, and provider-specific gotchas for each supported integration.
Implement advanced SLAS authentication patterns in B2C Commerce. Use when implementing passwordless login (email OTP, SMS OTP, passkeys), session bridging between PWA and SFRA, hybrid authentication, token refresh, or trusted system authentication. Covers authentication flows, token management, and JWT validation.
Retrieve staging credentials/JWT token for the Aircall dashboard
Build and debug Enable Banking API integrations for account information (AIS), payment initiation (PIS), ASPSP discovery, user sessions, JWT authentication with RSA certificates, sandbox setup, and TypeScript/Node clients. Use when Codex needs to implement Enable Banking request flows, generate or validate bearer JWTs, model Enable Banking schemas, handle PSU redirect callbacks, fetch accounts/balances/transactions, create payments, or troubleshoot Enable Banking API errors.
Tests API authentication mechanisms for weaknesses including broken token validation, missing authentication on endpoints, weak password policies, credential stuffing susceptibility, token leakage in URLs or logs, and session management flaws. The tester evaluates JWT implementation, API key handling, OAuth flows, and session token entropy to identify authentication bypasses. Maps to OWASP API2:2023 Broken Authentication. Activates for requests involving API authentication testing, token validation assessment, credential security testing, or API auth bypass.
