jsSha HMAC 与加密不匹配 - OTP 算法

Question

这两个代码 return 不一样。对不起，我不是这两个库的专家。

const jsSHA = require("jssha");

const time = "00000000030f7141"
const key = "101010"
var shaObj = new jsSHA("SHA-1", "HEX");
shaObj.setHMACKey(key, "HEX");
shaObj.update(time);
const hmac = shaObj.getHMAC("HEX");
console.log(hmac) 
// returns '536d6eed86796085f8ec2ead742c52fd73995f27'
---------------
const crypto = require('crypto')

const time = "00000000030f7141"
const key = "101010"
crypto.createHmac('sha1', new Buffer(key, 
'HEX')).update(time).digest('HEX')
// returns '8a3df92d2a68b32b2b571a1b71bfea03556e0df4'

我的观点是避免使用外部库来将 OTP 与 Google 身份验证器一起使用。最好的，

您的 nodejs update() 也不例外。你也需要在那里使用十六进制。

附上示例代码

const jsSHA = require("jssha");

const time = "00000000030f7141"
const key = "101010"
var shaObj = new jsSHA("SHA-1", "HEX");
shaObj.setHMACKey(key, "HEX");
shaObj.update(time);
const hmac = shaObj.getHMAC("HEX");
console.log(hmac) 
// returns '536d6eed86796085f8ec2ead742c52fd73995f27'
const crypto = require('crypto')

let out = crypto.createHmac('sha1', new Buffer(key, 'hex')).update(new Buffer(time,'hex')).digest('hex')
// returns '536d6eed86796085f8ec2ead742c52fd73995f27'
console.log(out)
