我正在学习区块链技术,并希望创建一个创建地址的示例,仅限于教育目的 - 不会在生产环境中使用。
任务:创建160个随机比特,将其转换为十六进制,再将其转换为base58,然后通过反向过程测试正确性。
这种方法有所作为,但是在比较二进制之前和之后出现了间歇性的 'false'。hexStringToBinary函数返回长度不同的字符串:
const bs58 = require('bs58');
//20 * 8 = 160
function generate20Bytes () {
let byteArray = [];
let bytes = 0;
while (bytes < 20) {
let byte = '';
while (byte.length < 8) {
byte += Math.floor(Math.random() * 2);
}
byteArray.push(byte);
bytes++;
}
return byteArray;
}
//the issue is probably from here
function hexStringToBinary (string) {
return string.match(/.{1,2}/g)
.map(hex => parseInt(hex, 16).toString(2).padStart(8, '0'));
}
const addressArray = generate20Bytes();
const binaryAddress = addressArray.join('');
const hex = addressArray.map(byte => parseInt(byte, 2).toString(16)).join('');
console.log(hex);
// then lets convert it to base 58
const base58 = bs58.encode(Buffer.from(hex));
console.log('base 58');
console.log(base58);
// lets see if we can reverse the process
const destructuredHex = bs58.decode(base58).toString();
console.log('hex is the same');
console.log(hex === destructuredHex);
// lets convert back to a binary string
const destructuredAddress = hexStringToBinary(destructuredHex).join('');
console.log('destructured address');
console.log(destructuredAddress);
console.log('binaryAddress address');
console.log(binaryAddress);
//intermittent false/true
console.log(destructuredAddress === binaryAddress);
