Struct RsaPublicKey 

pub struct RsaPublicKey { /* private fields */ }

Available on crate feature rsa only.

Represents the public part of an RSA key.

Implementations

impl RsaPublicKey

pub fn encrypt<R, P>( &self, rng: &mut R, padding: P, msg: &[u8], ) -> Result<Vec<u8>, Error>

where R: CryptoRng + ?Sized, P: PaddingScheme,

Encrypt the given message.

pub fn verify<S>( &self, scheme: S, hashed: &[u8], sig: &[u8], ) -> Result<(), Error>

where S: SignatureScheme,

Verify a signed message.

hashed must be the result of hashing the input using the hashing function passed in through hash.

If the message is valid Ok(()) is returned, otherwise an Err indicating failure.

impl RsaPublicKey

pub const MIN_PUB_EXPONENT: u64 = 2u64

Minimum value of the public exponent e.

pub const MAX_PUB_EXPONENT: u64 = 8_589_934_591u64

Maximum value of the public exponent e.

pub const MAX_SIZE: usize = 4_096usize

Maximum size of the modulus n in bits.

pub fn new(n: BoxedUint, e: BoxedUint) -> Result<RsaPublicKey, Error>

Create a new public key from its components.

This function accepts public keys with a modulus size up to 4096-bits, i.e. RsaPublicKey::MAX_SIZE.

pub fn new_with_max_size( n: BoxedUint, e: BoxedUint, max_size: usize, ) -> Result<RsaPublicKey, Error>

Create a new public key from its components.

pub fn new_unchecked(n: BoxedUint, e: BoxedUint) -> RsaPublicKey

Create a new public key, bypassing checks around the modulus and public exponent size.

This method is not recommended, and only intended for unusual use cases. Most applications should use RsaPublicKey::new or RsaPublicKey::new_with_max_size instead.

Trait Implementations

impl AsRef<RsaPublicKey> for RsaPrivateKey

fn as_ref(&self) -> &RsaPublicKey

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for RsaPublicKey

fn clone(&self) -> RsaPublicKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RsaPublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<&RsaPrivateKey> for RsaPublicKey

fn from(private_key: &RsaPrivateKey) -> RsaPublicKey

Converts to this type from the input type.

impl<'a> From<&'a RsaPublicKey> for JsonWebKey<'a>

fn from(key: &'a RsaPublicKey) -> JsonWebKey<'a>

Converts to this type from the input type.

impl From<RsaPrivateKey> for RsaPublicKey

fn from(private_key: RsaPrivateKey) -> RsaPublicKey

Converts to this type from the input type.

impl<D> From<VerifyingKey<D>> for RsaPublicKey

where D: Digest,

fn from(key: VerifyingKey<D>) -> RsaPublicKey

Converts to this type from the input type.

impl<D> From<VerifyingKey<D>> for RsaPublicKey

where D: Digest,

fn from(key: VerifyingKey<D>) -> RsaPublicKey

Converts to this type from the input type.

impl Hash for RsaPublicKey

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

where H: Hasher,

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PublicKeyParts for RsaPublicKey

fn n(&self) -> &NonZero<BoxedUint>

Returns the modulus of the key.

fn e(&self) -> &BoxedUint

Returns the public exponent of the key.

fn n_params(&self) -> &BoxedMontyParams

Returns the parameters for montgomery operations.

fn size(&self) -> usize

Returns the modulus size in bytes. Raw signatures and ciphertexts for or by this public key will have the same size.

fn n_bits_precision(&self) -> u32

Returns precision (in bits) of n.

fn n_bytes(&self) -> Box<[u8]>

Returns the big endian serialization of the modulus of the key

fn e_bytes(&self) -> Box<[u8]>

Returns the big endian serialization of the public exponent of the key

impl TryFrom<&JsonWebKey<'_>> for RsaPublicKey

type Error = JwkError

The type returned in the event of a conversion error.

fn try_from(jwk: &JsonWebKey<'_>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<RsaPublicKey> for StrongKey<RsaPublicKey>

type Error = WeakKeyError<RsaPublicKey>

The type returned in the event of a conversion error.

fn try_from(key: RsaPublicKey) -> Result<Self, Self::Error>

Performs the conversion.
