Implementations§

Source§

impl EcElGamal

Source

pub fn encrypt<P, const LIMBS: usize>( base_point: &P, recipient_public: &P, message: &P, ephemeral_secret: &SecretScalar<LIMBS>, curve: &P::Curve, ) -> Option<Ciphertext<P>>
where P: PointAdd,

Encrypt a point message using a recipient public key and an application-provided ephemeral scalar.

Source

pub fn decrypt<P, const LIMBS: usize>( recipient_secret: &SecretScalar<LIMBS>, ciphertext: &Ciphertext<P>, curve: &P::Curve, ) -> P
where P: PointAdd,

Decrypt an ElGamal ciphertext back to the original point message.
