Struct DecapsulationKey

pub struct DecapsulationKey<Id = AlgorithmId>
where
    Id: AlgorithmIdentifier,
{ /* private fields */ }

A serializable decapulsation key usable with KEMs. This can be randomly generated with DecapsulationKey::generate.

Implementations

impl<Id> DecapsulationKey<Id>

where Id: AlgorithmIdentifier,

pub fn generate(alg: &'static Algorithm<Id>) -> Result<Self, Unspecified>

Generate a new KEM decapsulation key for the given algorithm.

Errors

error::Unspecified when operation fails due to internal error.

pub fn algorithm(&self) -> &'static Algorithm<Id>

Return the algorithm associated with the given KEM decapsulation key.

pub fn encapsulation_key(&self) -> Result<EncapsulationKey<Id>, Unspecified>

Computes the KEM encapsulation key from the KEM decapsulation key.

Errors

error::Unspecified when operation fails due to internal error.

pub fn decapsulate( &self, ciphertext: Ciphertext<'_>, ) -> Result<SharedSecret, Unspecified>

Performs the decapsulate operation using this KEM decapsulation key on the given ciphertext.

ciphertext is the ciphertext generated by the encapsulate operation using the KEM encapsulation key associated with this KEM decapsulation key.

Errors

Unspecified when operation fails due to internal error.
