1.0.0

Neptune 1.0.0

We're excited to announce the first stable release of Neptune! A high-performance Swift package providing secp256k1 elliptic curve cryptography functionality, built on top of bitcoin-core/secp256k1.

✨ Features

• ✅ ECDSA Signatures - Create and verify signatures with compact (64-byte) and DER (70-72 byte) formats
• ✅ Key Management - Generate and serialize secret/public keys in compressed (33-byte) and uncompressed (65-byte) formats
• ✅ Recoverable Signatures - Recover public keys from signatures and message hashes
• ✅ Swift-Native API - Clean, type-safe Swift interface with comprehensive error handling
• ✅ Security - Context randomization, automatic secret key memory clearing, input validation
• ✅ Performance - Built on optimized secp256k1 with static context support for zero-allocation operations

📦 Requirements

• Swift 6.0+
• iOS 15.0+ / macOS 13.0+ / tvOS 15.0+ / watchOS 8.0+ / visionOS 1.0+

🚀 Installation

    .package(url: "https://github.com/bespalov-software/Neptune.git", from: "1.0.0")
]

📚 Quick Start

import Neptune

let secp256k1 = try SECP256K1()
let secretKey = try secp256k1.secretKey()
let publicKey = try secp256k1.publicKey(secretKey: secretKey)

// Sign and verify
let signature = try secretKey.sign(messageHash: messageHash)
let isValid = publicKey.verify(signature: signature, messageHash: messageHash)

// Recoverable signatures
let recoverableSig = try secretKey.signRecoverable(messageHash: messageHash)
let recoveredKey = SECP256K1.PubKey.recover(signature: recoverableSig, messageHash: messageHash)
