Trait KeyTransportKey 

pub trait KeyTransportKey: Send + Sync {
    // Required methods
    fn rsa_modulus(&self) -> Cow<'_, [u8]>;
    fn rsa_exponent(&self) -> Cow<'_, [u8]>;
    fn transport_with_provider(
        &self,
        provider: &dyn CryptoProvider,
        parameters: &RsaOaepParameters,
        plaintext: &[u8],
    ) -> Result<Vec<u8>, ProviderError>;
}

Opaque public-key handle used for asymmetric key transport.

Implementations own their key material and operation. The orchestration layer can inspect only public RSA components needed for policy validation and output framing; it cannot recover a backend-specific key object.

Required Methods

fn rsa_modulus(&self) -> Cow<'_, [u8]>

RSA modulus bytes without redundant leading zero octets.

These components must identify the exact key used by Self::transport_with_provider; returning metadata for another key would violate the policy boundary.

fn rsa_exponent(&self) -> Cow<'_, [u8]>

RSA public exponent bytes without redundant leading zero octets.

fn transport_with_provider( &self, provider: &dyn CryptoProvider, parameters: &RsaOaepParameters, plaintext: &[u8], ) -> Result<Vec<u8>, ProviderError>

Execute OAEP key transport using the selected provider’s randomness.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
