Struct jwt_compact::alg::RsaPublicKey

pub struct RsaPublicKey { /* private fields */ }

Available on crate feature rsa only.

Represents the public part of an RSA key.

Implementations

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: BigUint, e: BigUint) -> 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: BigUint, e: BigUint, max_size: usize ) -> Result<RsaPublicKey, Error>

Create a new public key from its components.

pub fn new_unchecked(n: BigUint, e: BigUint) -> 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 Clone for RsaPublicKey

fn clone(&self) -> RsaPublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RsaPublicKey

Formats the value using the given formatter.

impl DecodePublicKey for RsaPublicKey

fn from_public_key_der(bytes: &[u8]) -> Result<Self, Error>

Deserialize object from ASN.1 DER-encoded [SubjectPublicKeyInfo] (binary format).

impl EncodePublicKey for RsaPublicKey

fn to_public_key_der(&self) -> Result<Document, Error>

Serialize a [Document] containing a SPKI-encoded public key.

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 From<RsaPrivateKey> for RsaPublicKey

fn from(private_key: RsaPrivateKey) -> RsaPublicKey

Converts to this type from the input type.

impl<D> From<VerifyingKey<D>> for RsaPublicKeywhere D: Digest,

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

Converts to this type from the input type.

impl<D> From<VerifyingKey<D>> for RsaPublicKeywhere 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,

impl PartialEq<RsaPublicKey> 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.
