Expand description
This type should be used to deserialize a received private key
Implementations§
source§impl PrivateKey
impl PrivateKey
sourcepub fn public_key(&self) -> PublicKey
pub fn public_key(&self) -> PublicKey
Obtain the public key part of a private key
sourcepub fn diffie_hellman(&self, remote_public_key: &PublicKey) -> [u8; 32]
pub fn diffie_hellman(&self, remote_public_key: &PublicKey) -> [u8; 32]
To perform a key exchange with another public key
sourcepub fn from_ed25519_private_bytes(
private_slice: &[u8]
) -> Result<Self, CryptoMaterialError>
pub fn from_ed25519_private_bytes( private_slice: &[u8] ) -> Result<Self, CryptoMaterialError>
Deserialize an X25119 PrivateKey given the sha512 pre-image of a hash whose least significant half is a canonical X25519 scalar, following the XEdDSA approach.
This will FAIL if the passed-in byte representation converts to a non-canonical scalar in the X25519 sense (and thus cannot correspond to a X25519 valid key without bit-mangling).
This is meant to compensate for the poor key storage capabilities of some key management solutions, and NOT to promote double usage of keys under several schemes, which would lead to BAD vulnerabilities.

associated type is each other.

source§fn generate<R>(rng: &mut R) -> Selfwhere
R: RngCore + CryptoRng,
fn generate<R>(rng: &mut R) -> Selfwhere R: RngCore + CryptoRng,
Generate key material from an RNG. This should generally not be used for production
purposes even with a good source of randomness. When possible use hardware crypto to generate and
store private keys.
