JWT¶

JWT is used for creating and verifying JSON Web Tokens.

It is commonly used for:

• Authentication
• Session management
• Secure data transfer between systems

JWT functionality is available through the modules object.

Creating a Token¶

const token = modules.JWT.sign(
  { userId: 123 },
  "secret"
)

This generates a signed token string.

Verifying a Token¶

const decoded = modules.JWT.verify(
  token,
  "secret"
)

This verifies the token and returns the decoded payload.

Example Output¶

token   → "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
decoded → { userId: 123, iat: 1690000000 }

Notes¶

• Tokens are cryptographically signed
• Use strong secrets or keys
• Verification fails if the token is invalid or expired
