Expand description

Implementation of the ElGamal cryptosystem over an elliptic curve.

Structs

CurveElGamal

ElGamal over the Ristretto-encoded Curve25519 elliptic curve. The curve is provided by the curve25519-dalek crate. ElGamal is a partially homomorphic cryptosystem.

CurveElGamalCiphertext

ElGamal ciphertext containing curve points. The addition operator on the ciphertext is reflected as the curve operation on the associated plaintext.
