Trait KeyRecoveryKey 

pub trait KeyRecoveryKey: Send + Sync {
    // Required methods
    fn ciphertext_len(&self) -> usize;
    fn recover_with_provider(
        &self,
        provider: &dyn CryptoProvider,
        parameters: &RsaOaepParameters,
        ciphertext: &[u8],
    ) -> Result<Vec<u8>, ProviderError>;
}

Opaque private-key handle used to recover transported key bytes.

Private key material never crosses this boundary. The ciphertext size is public metadata required to reject malformed RSA inputs before dispatch.

Required Methods

fn ciphertext_len(&self) -> usize

Exact RSA ciphertext width in bytes for the key used by Self::recover_with_provider.

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

Execute OAEP recovery using the selected provider’s randomness.

Dyn Compatibility

This trait is dyn compatible.

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