Trait Implementations

impl EcdhArrayref<RAND_LEN, SECRET_LEN, PUBLIC_LEN> for X25519

fn generate_secret( secret: &mut [U8; 32], rand: &[U8; 32], ) -> Result<(), GenerateSecretError>

Generate a Diffie-Hellman secret value. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn secret_to_public( public: &mut [u8; 32], secret: &[U8; 32], ) -> Result<(), SecretToPublicError>

Derive a Diffie-Hellman public value from a secret value.

fn derive_ecdh( derived: &mut [U8; 32], public: &[u8; 32], secret: &[U8; 32], ) -> Result<(), DeriveError>

Derive a Diffie-Hellman shared secret from a public and a secret value.

fn validate_secret(secret: &[U8; 32]) -> Result<(), ValidateSecretError>

Check the validity of a Diffie-Hellman secret value.

fn generate_pair( public: &mut [u8; PUBLIC_LEN], secret: &mut [u8; SECRET_LEN], rand: &[u8; RAND_LEN], ) -> Result<(), GenerateSecretError>

Generate a Diffie-Hellman secret value and derive the corresponding public value in one step.

impl EcdhSlice for X25519

fn generate_secret( secret: &mut [U8], rand: &[U8], ) -> Result<(), GenerateSecretError>

Generate a Diffie-Hellman secret value. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn secret_to_public( public: &mut [u8], secret: &[U8], ) -> Result<(), SecretToPublicError>

Derive a Diffie-Hellman public value from a secret value.

fn derive_ecdh( derived: &mut [U8], public: &[u8], secret: &[U8], ) -> Result<(), DeriveError>

Derive a Diffie-Hellman shared secret from a public and a secret value.

fn validate_secret(secret: &[U8]) -> Result<(), ValidateSecretError>

Check the validity of a Diffie-Hellman secret value.

fn generate_pair( public: &mut [u8], secret: &mut [u8], rand: &[u8], ) -> Result<(), GenerateSecretError>

Generate a Diffie-Hellman secret value and derive the corresponding public value in one step.

impl Kem<DK_LEN, EK_LEN, EK_LEN, SS_LEN, DK_LEN, DK_LEN> for X25519

fn keygen( ek: &mut [u8; 32], dk: &mut [U8; 32], rand: &[U8; 32], ) -> Result<(), KeyGenError>

Generate a pair of encapsulation and decapsulation keys. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn encaps( ct: &mut [u8; 32], ss: &mut [U8; 32], ek: &[u8; 32], rand: &[U8; 32], ) -> Result<(), EncapsError>

Encapsulate a shared secret towards a given encapsulation key. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn decaps( ss: &mut [U8; 32], ct: &[u8; 32], dk: &[U8; 32], ) -> Result<(), DecapsError>

Decapsulate a shared secret.

impl Kem for X25519

fn keygen(ek: &mut [u8], dk: &mut [U8], rand: &[U8]) -> Result<(), KeyGenError>

Generate a pair of encapsulation and decapsulation keys. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn encaps( ct: &mut [u8], ss: &mut [U8], ek: &[u8], rand: &[U8], ) -> Result<(), EncapsError>

Encapsulate a shared secret towards a given encapsulation key. It is the responsibility of the caller to ensure that the rand argument is actually random.

fn decaps(ss: &mut [U8], ct: &[u8], dk: &[U8]) -> Result<(), DecapsError>
