Struct rsa::RSAPrivateKey

pub struct RSAPrivateKey { /* private fields */ }

Represents a whole RSA key, public and private parts.

Implementations

impl RSAPrivateKey

pub fn new<R: Rng>(rng: &mut R, bit_size: usize) -> Result<RSAPrivateKey>

Generate a new RSA key pair of the given bit size using the passed in rng.

pub fn from_components(
    n: BigUint,
    e: BigUint,
    d: BigUint,
    primes: Vec<BigUint>
) -> RSAPrivateKey

Constructs an RSA key pair from the individual components.

pub fn precompute(&mut self)

Performs some calculations to speed up private key operations.

pub fn d(&self) -> &BigUint

Returns the private exponent of the key.

pub fn primes(&self) -> &[BigUint]

Returns the prime factors.

pub fn validate(&self) -> Result<()>

Performs basic sanity checks on the key. Returns Ok(()) if everything is good, otherwise an approriate error.

pub fn decrypt(
    &self,
    padding: PaddingScheme,
    ciphertext: &[u8]
) -> Result<Vec<u8>>

Decrypt the given message.

pub fn decrypt_blinded<R: Rng>(
    &self,
    rng: &mut R,
    padding: PaddingScheme,
    ciphertext: &[u8]
) -> Result<Vec<u8>>

Decrypt the given message. Uses rng to blind the decryption process.

pub fn sign<H: Hash>(
    &self,
    padding: PaddingScheme,
    hash: Option<&H>,
    digest: &[u8]
) -> Result<Vec<u8>>

Sign the given digest.

pub fn sign_blinded<R: Rng, H: Hash>(
    &self,
    rng: &mut R,
    padding: PaddingScheme,
    hash: Option<&H>,
    digest: &[u8]
) -> Result<Vec<u8>>

Sign the given digest. Use rng for blinding.

Trait Implementations

impl Clone for RSAPrivateKey

fn clone(&self) -> RSAPrivateKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RSAPrivateKey

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

Formats the value using the given formatter.

impl From<RSAPrivateKey> for RSAPublicKey

fn from(private_key: RSAPrivateKey) -> Self

impl<'a> PublicKey for &'a RSAPrivateKey

fn n(&self) -> &BigUint

Returns the modulus of the key.

fn e(&self) -> &BigUint

Returns the public exponent of the key.

fn size(&self) -> usize
