Node.js使用AES加密大文件

您可以将加密的文件写回到磁盘，而不是将整个内容缓存在内存中：

var fs = require('fs');var crypto = require('crypto');var key = '14189dc35ae35e75ff31d7502e245cd9bc7803838fbfd5c773cdcd79b8a28bbd';var cipher = crypto.createCipher('aes-256-cbc', key);var input = fs.createReadStream('test.txt');var output = fs.createWriteStream('test.txt.enc');input.pipe(cipher).pipe(output);output.on('finish', function() {  console.log('Encrypted file written to disk!');});
