为什么以下代码会在加密中引发 DecipherFinal 错误 -
var crypto = require('crypto');
c=new Date;
x= (c.getTime()+"."+c.getMilliseconds()).toString()+".uIn";
key = 'sevsolut'
, plaintext = x
, cipher = crypto.createCipher('aes-256-cbc', key)
, decipher = crypto.createDecipher('aes-256-cbc', key);
cipher.update(plaintext, 'utf8', 'base64');
var encryptedPassword = cipher.final('base64')
decipher.update(encryptedPassword, 'base64', 'utf8');
var decryptedPassword = decipher.final('utf8');
console.log('encrypted :', encryptedPassword);
console.log('decrypted :', decryptedPassword);
