Struct RustCryptoX448Key 

pub struct RustCryptoX448Key(/* private fields */);

Opaque RustCrypto X448 private key, zeroized on drop without secret export.

Implementations

impl RustCryptoX448Key

pub fn from_bytes(bytes: [u8; 56]) -> Self

Import a 56-byte scalar; clamping follows RFC 7748 section 5.

pub fn from_pkcs8_der(bytes: &[u8]) -> Result<Self, ProviderError>

Import RFC 8410 PKCS#8, validating any included public-key identity. DER is borrowed; only the fixed-width scalar enters the zeroizing key.

pub fn public_key(&self) -> [u8; 56]

Return the RFC 7748 section 5 little-endian public u-coordinate.

Trait Implementations

impl Debug for RustCryptoX448Key

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

Formats the value using the given formatter.

impl KeyAgreementKey for RustCryptoX448Key

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.
