JWT Key Generator

This tool generates cryptographic signing keys for JSON Web Tokens (JWT) using RSA or EC algorithms. It supports common key sizes and curves, and exports outputs in standard formats suitable for integration into token issuance workflows. The process creates a key pair, derives necessary JWK fields, and can assign a key ID (kid) for key rotation and easy verification. Users choose an algorithm, size or curve, and desired formats, then receive private and public keys, with optional JWK/JWKS payloads. The service does not store keys, ensuring ephemeral generation and reducing exposure. Core value lies in eliminating boilerplate crypto setup, aligning with JWT standards, and streamlining secure onboarding of signing material for APIs, gateways, and microservices. Typical use cases include API authentication, OAuth token issuance, and service-to-service auth where tokens must be verifiable by multiple services. Outputs are compatible with common crypto stacks and JWT libraries, enabling immediate integration with token signing pipelines. Adheres to RFC 7518 for JWK structure and standard PEM/PKCS#8 formats, supporting easy import into existing security infrastructure. This tool is designed for developers, security engineers, and IT teams seeking rapid, standards-compliant key provisioning without storage or external dependencies.
