Solana生成离线地址（Java）
钱包
-
BIP32：定义 Hierarchical Deterministic wallet (简称 “HD Wallet”)，是一个系统可以从单一个 seed 产生一树状结构储存多组 keypairs（私钥和公钥）。好处是可以方便的备份、转移到其他相容装置（因为都只需要 seed），以及分层的权限控制等。
-
BIP39：将 seed 用方便记忆和书写的单字表示。一般由 12 个单字组成，称为 mnemonic code(phrase)，中文称为助记词或助记码。例如：
soldier dish answer treat exhibit blade diary glory arrange shoe ocean card
- BIP44：基于 BIP32 的系统，赋予树状结构中的各层特殊的意义。让同一个 seed 可以支援多币种、多帐户等。各层定义如下：
m / purpose' / coin_type' / account' / change / address_index
//purporse': 固定值44', 代表是BIP44
//coin_type': 这个代表的是币种, 可以兼容很多种币, 比如BTC是0, ETH是60,TRX是195
//account: 代表这个币的账户索引，从0开始
//change: 常量0用于外部(收款地址)，常量1用于内部（也称为找零地址）。外部用于在钱包外可见的地址（例如，用于接收付款）。内部链用于在钱包外部不可见的地址，用于返回交易变更。 (所以一般使用0)
//address_index: 地址索引，从0开始，代表生成第几个地址
//btc一般是 m/44'/0'/0'/0
//eth一般是 m/44'/60'/0'/0
//trx一般是 m/44'/195'/0'/0

生成地址及私钥
byte[] seed = MnemonicUtils.generateSeed(mnemonic, "");
SolanaBip44 solanaBip44 = new SolanaBip44();
//M/44H/501H/0H/0H
byte[] privateKeyFromSeed = solanaBip44.getPrivateKeyFromSeed(seed, DerivableType.BIP44CHANGE);
TweetNaclFast.Signature.KeyPair keyPair = TweetNaclFast.Signature.keyPair_fromSeed(privateKeyFromSeed);
System.out.println("地址0：" + Base58.encode(keyPair.getPublicKey()));
System.out.println("私钥0：" + Base58.encode(keyPair.getSecretKey()));
Account account = new Account(keyPair);
System.out.println("Account地址0：" + account.getPublicKey());
System.out.println("Account私钥0：" + Base58.encode(account.getSecretKey()));
BIP44助记词生成N个地址
//拆解 getPrivateKeyFromSeed(seed, DerivableType.BIP44CHANGE);
for (int i = 0; i < 10; i++) {
HdKeyGenerator hdKeyGenerator = new HdKeyGenerator();
SolanaCoin solanaCoin = new SolanaCoin();
HdAddress masterAddress = hdKeyGenerator.getAddressFromSeed(seed, solanaCoin);
HdAddress purposeAddress = hdKeyGenerator.getAddress(masterAddress, solanaCoin.getPurpose(), solanaCoin.getAlwaysHardened());// 44H
HdAddress coinTypeAddress = hdKeyGenerator.getAddress(purposeAddress, solanaCoin.getCoinType(), solanaCoin.getAlwaysHardened());// 501H
HdAddress accountAddress = hdKeyGenerator.getAddress(coinTypeAddress, i, solanaCoin.getAlwaysHardened());//0H
HdAddress changeAddress = hdKeyGenerator.getAddress(accountAddress, 0L, solanaCoin.getAlwaysHardened()); //0H
Account account1 = new Account(TweetNaclFast.Signature.keyPair_fromSeed(changeAddress.getPrivateKey().getPrivateKey()));
System.out.println("Account地址" + i + "：" + account1.getPublicKey());
System.out.println("Account私钥" + i + "：" + Base58.encode(account1.getSecretKey()));
}
