Module schnorr 

Schnorr signatures for simplicity and provable security.

Schnorr signatures provide:

• Simpler construction than EdDSA with cleaner security proofs
• Provable security under the discrete logarithm assumption
• Native support for threshold signatures
• Batch verification support
• Linear signature aggregation

Example

use chie_crypto::schnorr::{SchnorrKeypair, batch_verify};

// Generate a keypair
let keypair = SchnorrKeypair::generate();
let message = b"Hello, Schnorr!";

// Sign a message
let signature = keypair.sign(message);

// Verify the signature
assert!(keypair.verify(message, &signature).is_ok());

// Batch verification
let items = vec![
    (keypair.public_key(), message.as_slice(), signature),
];
assert!(batch_verify(&items).is_ok());
