Struct EncapsulationKey 

pub struct EncapsulationKey<P>
where
    P: KemParams,
{ /* private fields */ }

An EncapsulationKey provides the ability to encapsulate a shared key so that it can only be decapsulated by the holder of the corresponding decapsulation key.

Trait Implementations

impl<P> AssociatedAlgorithmIdentifier for EncapsulationKey<P>

where P: KemParams + AssociatedAlgorithmIdentifier<Params = AnyRef<'static>>,

Available on crate feature pkcs8 only.

Encapsulates a fresh shared secret

impl<P> EncapsulateDeterministic<Array<u8, <P as PkeParams>::CiphertextSize>, Array<u8, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>>> for EncapsulationKey<P>

where P: KemParams,

Available on crate feature deterministic only.

type Error = Infallible

Encapsulation error

fn encapsulate_deterministic( &self, m: &B32, ) -> Result<(Array<u8, <P as PkeParams>::CiphertextSize>, B32), Self::Error>

Encapsulates a fresh shared secret.

impl<P> EncodePublicKey for EncapsulationKey<P>

where P: KemParams + AssociatedAlgorithmIdentifier<Params = AnyRef<'static>>,

Available on crate features pkcs8 and alloc only.

fn to_public_key_der(&self) -> Result<Document>

Serialize the given EncapsulationKey into DER format. Returns a Document which wraps the DER document in case of success.

fn to_public_key_pem(&self, line_ending: LineEnding) -> Result<String, Error>

Serialize this public key as PEM-encoded SPKI with the given LineEnding.

impl<P> EncodedSizeUser for EncapsulationKey<P>

where P: KemParams,

Serialize an object to its encoded form

impl<P> PartialEq for EncapsulationKey<P>

where P: KemParams + PartialEq,

fn eq(&self, other: &EncapsulationKey<P>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
