Struct KeyPair 

pub struct KeyPair(/* private fields */);

An RSA private key.

This is not so useful at present, since Arti currently only has client support, and Tor clients never actually need RSA private keys.

Implementations

impl KeyPair

pub fn generate<R: RngCore + CryptoRng>(csprng: &mut R) -> Result<Self, Bug>

Generate a new random RSA keypair.

This is hardcoded to generate a 1024-bit keypair, since this only exists to support the RSA keys that we require for backwards compatibility (which are all 1024 bit), and we don’t anticipate adding anything new that uses RSA in the future.

pub fn to_public_key(&self) -> PublicKey

Return the public component of this key.

pub fn from_der(der: &[u8]) -> Option<Self>

Construct a PrivateKey from DER pkcs1 encoding.

pub fn as_key(&self) -> &RsaPrivateKey

Return a reference to the underlying key type.

pub fn sign(&self, message: &[u8]) -> Result<Vec<u8>, Error>

Sign a message using this keypair.

This uses PKCS#1 v1.5 padding and takes a raw bytes, rather than doing the hashing internally. This is because we use PKCS padding without specifying the hash OID, which is a slightly unusual setup that is understandably not supported by the rsa crate.

Trait Implementations

impl<'a> From<&'a KeyPair> for PublicKey

fn from(value: &'a KeyPair) -> Self

impl From<RsaPrivateKey> for KeyPair

fn from(value: RsaPrivateKey) -> Self
