fn write_public_key_pem_file( &self, path: impl AsRef<Path>, line_ending: LineEnding ) -> Result<(), Error>

impl From<&RsaPrivateKey> for RsaPublicKey

fn from(private_key: &RsaPrivateKey) -> Self

Converts to this type from the input type.

impl From<RsaPrivateKey> for RsaPublicKey

fn from(private_key: RsaPrivateKey) -> Self

Converts to this type from the input type.

impl Hash for RsaPublicKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RsaPublicKey

fn eq(&self, other: &RsaPublicKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> PublicKey for &'a RsaPublicKey

fn encrypt<R: RngCore + CryptoRng>( &self, rng: &mut R, padding: PaddingScheme, msg: &[u8] ) -> Result<Vec<u8>>

Encrypt the given message.
