Crate arcanum_signatures 

Arcanum Digital Signatures

High-performance digital signature algorithms with a unified interface.

Supported Algorithms

Edwards Curves

• Ed25519: Fast, secure, widely used. Recommended default.

ECDSA (Elliptic Curve Digital Signature Algorithm)

• ECDSA-P256: NIST P-256 curve, widely supported
• ECDSA-P384: NIST P-384 curve, higher security level
• ECDSA-secp256k1: Bitcoin/Ethereum curve

Schnorr Signatures

• Schnorr-secp256k1: BIP-340 compatible (Bitcoin Taproot)

Example

use arcanum_signatures::{Ed25519, SigningKey};

// Generate a new key pair
let signing_key = Ed25519::generate();
let verifying_key = signing_key.verifying_key();

// Sign a message
let message = b"Hello, Arcanum!";
let signature = signing_key.sign(message);

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

Security Considerations

• Always use fresh randomness for key generation
• Protect signing keys from exposure
• Ed25519 provides deterministic signatures (no additional randomness needed)
• ECDSA requires secure random nonces (use deterministic RFC 6979 variant)
