简介
这是一个Bip44确定性算法的Android实现库,可以生成12个助记词,seed种子和根据path路径生成路径的私钥.
对Bip44确定算法不了解的可以看我之前的一篇文章:

- 如何使用
代码如下:
//get 12 words List<String> words = Bip44Utils.generateMnemonicWords(MainActivity.this); Log.e("TAG", "words: " + words.toString()); // get bip39 seed byte[] seed = Bip44Utils.getSeed(words); Log.e("TAG", "seed: " + new BigInteger(1,seed).toString(16)); //get PrivateKey by path BigInteger pri1 = Bip44Utils.getPathPrivateKey(words,"m/44'/194'/0'/0/0"); Log.e("TAG", "pri1: " + pri1.toString(16)); BigInteger pri2 = Bip44Utils.getPathPrivateKey(words,seed,"m/44'/194'/0'/0/0"); Log.e("TAG", "pri2: " + pri2.toString(16)); byte[] pri3 = Bip44Utils.getPathPrivateKeyBytes(words, "m/44'/194'/0'/0/0"); Log.e("TAG", "pri3: " + new BigInteger(1,pri3).toString(16)); byte[] pri4 = Bip44Utils.getPathPrivateKeyBytes(words, seed,"m/44'/194'/0'/0/0"); Log.e("TAG", "pri4: " + new BigInteger(1,pri4).toString(16)); byte[] pri5 = Bip44Utils.getDefaultPathPrivateKeyBytes(words, 194); Log.e("TAG", "pri5: " + new BigInteger(1,pri5).toString(16)); //if you use bitcoinj library,you can generate bitcoin privatekey and public key and address like this: BigInteger pribtc = Bip44Utils.getPathPrivateKey(words,"m/44'/0'/0'/0/0"); ECKey ecKey = ECKey.fromPrivate(pribtc); String publicKey = ecKey.getPublicKeyAsHex(); String privateKey = ecKey.getPrivateKeyEncoded(networkParameters).toString(); String address = ecKey.toAddress(networkParameters).toString(); //if you use web3j library,you can generate bitcoin privatekey and public key and address like this: BigInteger prieth = Bip44Utils.getPathPrivateKey(words,"m/44'/60'/0'/0/0"); ECKeyPair ecKeyPair = ECKeyPair.create(prieth); String publicKey = Numeric.toHexStringWithPrefix(ecKeyPair.getPublicKey()); String privateKey = Numeric.toHexStringWithPrefix(ecKeyPair.getPrivateKey()); String address = "0x" + Keys.getAddress(ecKeyPair);
打印结果:
words: [course, question, calm, west, basket, kitten, salmon, absorb, tool, ankle, mixed, endorse]seed: c03f5488370482658066b96a803fcceac46b68181024a545d814344cbf7d9da9b478a20d0b95ebef268b7c24afd4540c59a4567146d45d2db891ca2576d409c7pri1: 6ef7a396546d4fcf26865e54033ad48db858d19b5a08782014a652f4b5469037pri2: 6ef7a396546d4fcf26865e54033ad48db858d19b5a08782014a652f4b5469037pri3: 6ef7a396546d4fcf26865e54033ad48db858d19b5a08782014a652f4b5469037pri4: 6ef7a396546d4fcf26865e54033ad48db858d19b5a08782014a652f4b5469037pri5: 6ef7a396546d4fcf26865e54033ad48db858d19b5a08782014a652f4b5469037
