Crate rust_elgamal

Structs

• Ciphertext
  An ElGamal ciphertext.
• CompressedRistretto
  A Ristretto point, in compressed wire format.
• DecryptionKey
  An ElGamal decryption key (also called a private key in other implementations).
• EncryptionKey
  An ElGamal encryption key (also called a public key in other implementations). To create a new encryption key, see DecryptionKey.
• RistrettoPoint
  A RistrettoPoint represents a point in the Ristretto group for Curve25519. Ristretto, a variant of Decaf, constructs a prime-order group as a quotient group of a subgroup of (the Edwards form of) Curve25519.
• Scalar
  The Scalar struct holds an integer \(s < 2^{255} \) which represents an element of \(\mathbb Z / \ell\).

Constants

• GENERATOR_POINT
  The group generator as a single point. If you’re trying to create a scalar multiple of the generator, you probably want GENERATOR_TABLE instead.
• GENERATOR_POINT_COMPRESSED
  The group generator as a single point, compressed for transit. If you’re trying to create a scalar multiple of the generator, you probably want GENERATOR_TABLE instead.
• GENERATOR_TABLE
  The group generator as a table of precomputed multiples. This is the most efficient way to produce a scalar multiple of the generator.

Traits

• Identity
  Trait for getting the identity element of a point type.
• IsIdentity
  Trait for testing if a curve point is equivalent to the identity point.
• MultiscalarMul
  A trait for constant-time multiscalar multiplication without precomputation.
