Struct RustCryptoRsaPrivateKey 

pub struct RustCryptoRsaPrivateKey { /* private fields */ }

Opaque RSA private-key handle for the built-in RustCrypto provider.

Implementations

impl RustCryptoRsaPrivateKey

pub fn new(key: RsaPrivateKey) -> Self

Wrap an already parsed RustCrypto RSA private key.

Trait Implementations

impl Clone for RustCryptoRsaPrivateKey

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<RsaPrivateKey> for RustCryptoRsaPrivateKey

Available on crate feature xmlenc only.

fn from(key: RsaPrivateKey) -> Self

Converts to this type from the input type.

impl KeyRecoveryKey for RustCryptoRsaPrivateKey

Available on crate feature xmlenc only.

fn rsa_modulus_bits(&self) -> usize

Exact mathematical bit length of the recovery key’s public modulus, excluding leading zero padding. Not the rounded ciphertext width.

fn rsa_public_exponent(&self) -> Option<u64>

Public exponent of that same key, or None if wider than 64 bits. Opaque providers expose public metadata without copying private material.

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.

fn recover_content_with_provider( &self, provider: &dyn CryptoProvider, parameters: &RsaOaepParameters, _content_algorithm: DataEncryptionAlgorithm, ciphertext: &[u8], ) -> Result<RecoveredContentKey, ProviderError>

Recover without exporting a CEK when supported by the execution domain.

fn provider_name(&self) -> Option<&'static str>

Native engine binding; an incompatible provider must reject this handle.

fn public_spki(&self) -> Option<&[u8]>

Borrow the matching public SPKI when available for certificate binding.
