A credential issuer signs a credential to generate a verifiable credential.

Required Methods

fn sign<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, credential: &'life1 Credential, linked_data_proof_options: Option<LinkedDataProofOptions>, key_id: Option<&'life2 str>, resolver: &'life3 dyn TrustchainResolver, context_loader: &'life4 mut ContextLoader, ) -> Pin<Box<dyn Future<Output = Result<Credential, IssuerError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

Signs a credential. An issuer attests to a credential by signing the credential with one of their private signing keys.
