Struct RustCryptoX25519Key 

pub struct RustCryptoX25519Key(/* private fields */);

Opaque RustCrypto X25519 private key. Its scalar is zeroized on drop and is never exposed through Debug or a byte-export accessor.

Implementations

impl RustCryptoX25519Key

pub fn from_bytes(bytes: [u8; 32]) -> Self

Import the 32-byte scalar encoding; clamping follows RFC 7748 section 5.

pub fn public_key(&self) -> [u8; 32]

Return the public u-coordinate encoding defined by RFC 7748 section 5.

Trait Implementations

impl Debug for RustCryptoX25519Key

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

Formats the value using the given formatter.

impl KeyAgreementKey for RustCryptoX25519Key

fn agree( &self, parameters: &KeyAgreementParameters<'_>, ) -> Result<Vec<u8>, ProviderError>

Derive the raw shared secret for the supplied peer and parameters.

fn dh_domain_bits(&self) -> Option<(usize, usize)>

Public modulus/subgroup bit widths for finite-field DH. Operations use these to recheck key strength under their own policy; no secret is exported.

fn provider_binding(&self) -> Option<&ProviderBinding>

External execution domain, when the private key resides outside this process.
