Required Methods§

Source

fn get_der_public_key<'a, 'b, 'async_trait>( &'a self, key_id: &'b str, ) -> Pin<Box<dyn Future<Output = AwsKmsResult<Vec<u8>>> + Send + 'async_trait>>
where Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait,

Fetches the DER-encoded public key from AWS KMS.

Source

fn sign_digest<'a, 'b, 'async_trait>( &'a self, key_id: &'b str, digest: [u8; 32], ) -> Pin<Box<dyn Future<Output = AwsKmsResult<Vec<u8>>> + Send + 'async_trait>>
where Self: 'async_trait, 'a: 'async_trait, 'b: 'async_trait,

Signs a digest using EcdsaSha256 spec. Returns DER-encoded signature
