Struct KemContext 

pub struct KemContext { /* private fields */ }

KEM context for key encapsulation operations

Implementations

impl KemContext

pub fn new() -> KemContext

Create a new KEM context with no provider

pub fn with_provider(provider: Box<dyn CryptoProvider>) -> KemContext

Create a new KEM context with a provider

pub fn with_default_provider() -> KemContext

Create a new KEM context with the default provider

pub fn set_provider(&mut self, provider: Box<dyn CryptoProvider>)

Set the cryptographic provider

pub fn provider(&self) -> Option<&dyn CryptoProvider>

Get the current provider

pub fn generate_keypair( &mut self, algorithm: Algorithm, randomness: Option<&[u8]>, ) -> Result<KemKeypair, Error>

Generate a keypair for the specified algorithm

pub fn encapsulate( &self, algorithm: Algorithm, public_key: &KemPublicKey, randomness: Option<&[u8]>, ) -> Result<(Vec<u8>, Vec<u8>), Error>

Encapsulate a key using the given public key

pub fn decapsulate( &self, algorithm: Algorithm, secret_key: &KemSecretKey, ciphertext: &[u8], ) -> Result<Vec<u8>, Error>

Decapsulate a key using the given secret key and ciphertext

pub fn is_initialized(&self) -> bool

Check if the context is initialized
