Question 1

How do I integrate Frank JWT with Actix-web for authentication?

Accepted Answer

Frank JWT doesn't provide built-in Actix-web middleware. You'll need to manually decode tokens in your handlers using the decode function and implement custom middleware. Refer to the library's examples for encoding and decoding to fit it into your route logic.

Question 2

Frank JWT vs jsonwebtoken crate: which is better for Rust?

Accepted Answer

Frank JWT offers broad algorithm support and a simple API, but jsonwebtoken might have more features like better claim validation and active maintenance. Choose Frank JWT if you need specific ECDSA support or prefer its interface, but jsonwebtoken for more comprehensive validation and community ecosystem.

Question 3

How to handle key rotation with Frank JWT?

Accepted Answer

Frank JWT requires manual key management. You can implement custom logic to load different keys based on token headers or timestamps during verification, but there's no built-in support for automatic rotation or JWKS.

Question 4

Does Frank JWT support JSON Web Key Set (JWKS)?

Accepted Answer

No, Frank JWT doesn't natively support JWKS. You need to fetch and parse JWKS externally, then extract keys to use with the library's encode and decode functions, adding extra steps for dynamic environments.

Question 5

How to add custom claim validation in Frank JWT?

Accepted Answer

After decoding with ValidationOptions, manually inspect the payload JSON for custom claims. Use the dangerous mode to skip built-in validation and implement your own checks, but ensure you handle security risks appropriately.

Question 6

Is Frank JWT secure for production use?

Accepted Answer

It implements standard cryptographic algorithms and focuses on security, but the incomplete claim validation means you must manually verify claims like issuer or audience. Review the code and add missing validations to avoid vulnerabilities in production.
