Static Public Member Functions
static const FixedBlock< PUBLIC_BYTES >	base_point () DECAF_NOEXCEPT
	Base point for a scalar multiplication.
static SecureBuffer	shared_secret (const FixedBlock< PUBLIC_BYTES > &pk, const FixedBlock< PRIVATE_BYTES > &scalar)
	Calculate and return a shared secret with public key.
static decaf_error_t DECAF_WARN_UNUSED	shared_secret_noexcept (FixedBuffer< PUBLIC_BYTES > &out, const FixedBlock< PUBLIC_BYTES > &pk, const FixedBlock< PRIVATE_BYTES > &scalar) DECAF_NOEXCEPT
	Calculate and write into out a shared secret with public key, noexcept version.
static SecureBuffer	DECAF_DEPRECATED ("Renamed to derive_public_key") generate_key(const FixedBlock< PRIVATE_BYTES > &scalar)
	Calculate and return a public key; equivalent to shared_secret(base_point(),scalar) but possibly faster.
static SecureBuffer	derive_public_key (const FixedBlock< PRIVATE_BYTES > &scalar)
	Calculate and return a public key; equivalent to shared_secret(base_point(),scalar) but possibly faster.
static void	derive_public_key_noexcept (FixedBuffer< PUBLIC_BYTES > &out, const FixedBlock< PRIVATE_BYTES > &scalar) DECAF_NOEXCEPT
	Calculate and return a public key into a fixed buffer; equivalent to shared_secret(base_point(),scalar) but possibly faster.
static void	generate_key_noexcept (FixedBuffer< PUBLIC_BYTES > &out, const FixedBlock< PRIVATE_BYTES > &scalar) DECAF_NOEXCEPT
	Calculate and return a public key into a fixed buffer; equivalent to shared_secret(base_point(),scalar) but possibly faster.

Static Public Attributes
static const size_t	PUBLIC_BYTES = DECAF_X25519_PUBLIC_BYTES
	Bytes in an X25519 public key.
static const size_t	PRIVATE_BYTES = DECAF_X25519_PRIVATE_BYTES
	Bytes in an X25519 private key.

void decaf::Ristretto::DhLadder::generate_key_noexcept ( FixedBuffer< PUBLIC_BYTES > & out, const FixedBlock< PRIVATE_BYTES > & scalar )

inlinestatic

Calculate and return a public key into a fixed buffer; equivalent to shared_secret(base_point(),scalar) but possibly faster.
