从字符串中获取哈希值,例如哈希值

Question

使用包哈希,我可以从数字中获取哈希(并编码y解码)

var Hashids = require("hashids"),
    hashids = new Hashids("this is my salt", 8);

var id = hashids.encode(1);

存在一些类似的包来从字符串获取哈希？(带编码/解码)

Answer 1

var Hashids = require("hashids");
var hashids = new Hashids("this is my salt");

var hex = Buffer('Hello World').toString('hex');
console.log (hex); // '48656c6c6f20576f726c64'

var encoded = hashids.encodeHex(hex);
console.log (encoded); // 'rZ4pPgYxegCarB3eXbg'

var decodedHex = hashids.decodeHex('rZ4pPgYxegCarB3eXbg');
console.log (decodedHex); // '48656c6c6f20576f726c64'

var string = Buffer('48656c6c6f20576f726c64', 'hex').toString('utf8');
console.log (string); // 'Hello World'
