Plugin that can validate JWT signatures and decode tokens

Required Methods

fn name(&self) -> &str

Returns the name of this provider (for debugging/logging)

fn validate_and_decode<'life0, 'life1, 'async_trait>( &'life0 self, token: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(Header, Value), ClaimsError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Attempt to validate the JWT signature and decode its header and claims

Returns the JWT header and raw claims as JSON if validation succeeds. Returns an error if the signature is invalid or decoding fails.

This method should:

• Decode the JWT header
• Find the appropriate key (e.g., by kid)
• Validate the signature
• Return raw claims for further processing

Provided Methods

fn refresh_keys<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), ClaimsError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Optional: refresh keys if this provider supports it (e.g., JWKS)
