JWT Encoder

Professional JWT token generator with customizable header, payload, and signature key.

What is JWT?
JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object.

Three Parts of JWT

  • Header - Contains token type and signing algorithm
  • Payload - Contains claims (user data)
  • Signature - Used to verify token authenticity

Main Use Cases

  • Authentication and Authorization
  • Secure Information Transfer
  • Single Sign-On (SSO)
  • API Authentication
User Guide
How to use this JWT encoder to generate secure tokens

Steps

  1. Configure header information (default HS256 algorithm)
  2. Add necessary claims in the payload
  3. Enter a secure secret key
  4. Click generate button to get JWT token

Security Tips

  • Use strong secret keys (at least 32 characters recommended)
  • Avoid including sensitive information in payload
  • Rotate keys periodically
  • Set reasonable expiration times
Header
The header typically consists of two parts: the type of token (JWT) and the signing algorithm.
Payload
The payload contains the claims. Claims are statements about an entity and additional data.
Secret Key
The secret key is used to create the signature. Keep this secure and never share it.
