Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4. To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes. ## Installation $ npm install base64id ## Usage var base64id = require('base64id'); var id = base64id.generateId(); base64id-0.1.0/lib/000077500000000000000000000000001205761313000136555ustar00rootroot00000000000000base64id-0.1.0/lib/base64id.js000066400000000000000000000044731205761313000156240ustar00rootroot00000000000000/*! * base64id v0.1.0 */ /** * Module dependencies */ var crypto = require('crypto'); /** * Constructor */ var Base64Id = function() { }; /** * Get random bytes * * Uses a buffer if available, falls back to crypto.randomBytes */ Base64Id.prototype.getRandomBytes = function(bytes) { var BUFFER_SIZE = 4096 var self = this; bytes = bytes || 12; if (bytes > BUFFER_SIZE) { return crypto.randomBytes(bytes); } var bytesInBuffer = parseInt(BUFFER_SIZE/bytes); var threshold = parseInt(bytesInBuffer*0.85); if (!threshold) { return crypto.randomBytes(bytes); } if (this.bytesBufferIndex == null) { this.bytesBufferIndex = -1; } if (this.bytesBufferIndex == bytesInBuffer) { this.bytesBuffer = null; this.bytesBufferIndex = -1; } // No buffered bytes available or index above threshold if (this.bytesBufferIndex == -1 || this.bytesBufferIndex > threshold) { if (!this.isGeneratingBytes) { this.isGeneratingBytes = true; crypto.randomBytes(BUFFER_SIZE, function(err, bytes) { self.bytesBuffer = bytes; self.bytesBufferIndex = 0; self.isGeneratingBytes = false; }); } // Fall back to sync call when no buffered bytes are available if (this.bytesBufferIndex == -1) { return crypto.randomBytes(bytes); } } var result = this.bytesBuffer.slice(bytes*this.bytesBufferIndex, bytes*(this.bytesBufferIndex+1)); this.bytesBufferIndex++; return result; } /** * Generates a base64 id * * (Original version from socket.io ) */ Base64Id.prototype.generateId = function () { var rand = new Buffer(15); // multiple of 3 for base64 if (!rand.writeInt32BE) { return Math.abs(Math.random() * Math.random() * Date.now() | 0).toString() + Math.abs(Math.random() * Math.random() * Date.now() | 0).toString(); } this.sequenceNumber = (this.sequenceNumber + 1) | 0; rand.writeInt32BE(this.sequenceNumber, 11); if (crypto.randomBytes) { this.getRandomBytes(12).copy(rand); } else { // not secure for node 0.4 [0, 4, 8].forEach(function(i) { rand.writeInt32BE(Math.random() * Math.pow(2, 32) | 0, i); }); } return rand.toString('base64').replace(/\//g, '_').replace(/\+/g, '-'); }; /** * Export */ exports = module.exports = new Base64Id(); base64id-0.1.0/package.json000066400000000000000000000005151205761313000153760ustar00rootroot00000000000000{ "name": "base64id" , "version": "0.1.0" , "description": "Generates a base64 id" , "author": "Kristian Faeldt " , "repository": { "type": "git" , "url": "https://github.com/faeldt/base64id.git" } , "main": "./lib/base64id.js" , "engines": { "node": ">= 0.4.0" } }
