Efficient pure-Rust library for the ElGamal additive homomorphic
encryption scheme using the Ristretto primer order group using the ristretto255
implementation in curve25519-dalek.
This library provides implementations of:
- Additively Homomorphic ElGamal Encryption and decryption.
- Zero Knowledge Proofs using the toolkit for proof generation
zkpsupporting proof generation and verification of correct encryption, correct decryption and knowledge of private key. - EdDSA generation and verification.
Important: while we have followed recommendations regarding the scheme itself, this library should currently be seen as an experimental implementation. In particular, no particular efforts have so far been made to harden it against non-cryptographic attacks, including side-channel attacks.
