# Semaphore-rs
|
|
|
|
Rust support library for Semaphore
|
|
|
|
## Example
|
|
|
|
```rust
|
|
use semaphore::{
|
|
identity::Identity, hash::Hash, poseidon_tree::PoseidonTree,
|
|
protocol::* };
|
|
use num_bigint::BigInt;
|
|
|
|
// generate identity
|
|
let id = Identity::new(b"hello");
|
|
|
|
// generate merkle tree
|
|
const LEAF: Hash = Hash::from_bytes_be([0u8; 32]);
|
|
|
|
let mut tree = PoseidonTree::new(21, LEAF);
|
|
let (_, leaf) = id.commitment().to_bytes_be();
|
|
tree.set(0, leaf.into());
|
|
|
|
let root: BigInt = tree.root().into();
|
|
dbg!(root);
|
|
|
|
let merkle_proof = tree.proof(0).expect("proof should exist");
|
|
let root = tree.root().into();
|
|
|
|
// change signal and external_nullifier here
|
|
let signal = "hello".as_bytes();
|
|
let external_nullifier = "123".as_bytes();
|
|
|
|
let nullifier_hash = generate_nullifier_hash(&id, external_nullifier);
|
|
|
|
let config = SnarkFileConfig {
|
|
zkey: "./snarkfiles/semaphore.zkey".to_string(),
|
|
wasm: "./snarkfiles/semaphore.wasm".to_string(),
|
|
};
|
|
|
|
let proof = generate_proof(&config, &id, &merkle_proof, external_nullifier, signal).unwrap();
|
|
let success = verify_proof(&config, &root, &nullifier_hash, signal, external_nullifier, &proof).unwrap();
|
|
