javascript – 在Node.js中$2y bcrypt哈希

我正在处理一个带有$2y哈希值的旧数据库.我已经挖了一下,在 the stack overflow上偶然发现了$2a和$2y之间的差异.

我查看了bcrypt的节点模块,它似乎只生成并比较了$2a哈希值.

我找到了一个产生2美元哈希的网站,所以我可以用bcrypt来测试它们.

这是一个$2y字符串helloworld哈希的例子.

helloworld:$2y$10$tRM7x9gGKhcAmpeqKEdhj.qRWCr4qoV1FU9se0Crx2hkMVNL2ktEW

似乎模块无法验证$2y哈希值.

这是我的考试.

var Promise = require('bluebird')
var bcrypt = require('bcrypt')

var string = 'helloworld'

Promise.promisifyAll(bcrypt)

// bcrypt.genSalt(10,function(err,salt) {
//   bcrypt.hash(string,salt,hash) {
//     console.log(hash)
//   })
// })

var hashesGeneratedUsingBcryptModule = [
  '$2a$10$6ppmIdlNEPwxWJskPaQ7l.d2fblh.GO6JomzrcpiD/hxGPOXA3Bsq','$2a$10$YmpoYCDHzdAPMbd9B8l48.hkSnylnAPbOym367FKIEPa0ixY.o4b.','$2a$10$Xfy3OPurrZEmbmmO0x1wGuFMdRTlmOgEMS0geg4wTj1vKcvXXjk06','$2a$10$mYgwmdPZjiEncp7Yh5UB1uyPkoyavxrYcOIzzY4mzSniGpI9RbhL.','$2a$10$dkBVTe2A2DAn24PUq1GZYe7AqL8WQqwOi8ZWBJAauOg60sk44DkOC'
]

var hashesGeneratedUsingAspirineDotOrg = [
  '$2y$10$MKgpAXLJkwx5tpijWX99Qek2gf/irwvp5iSfxuFoDswIjMIbj2.Ma','$2y$10$tRM7x9gGKhcAmpeqKEdhj.qRWCr4qoV1FU9se0Crx2hkMVNL2ktEW'
]

var hashesGeneratedUsingAspirineDotOrgSwippedYForA = [
  '$2a$10$MKgpAXLJkwx5tpijWX99Qek2gf/irwvp5iSfxuFoDswIjMIbj2.Ma','$2a$10$tRM7x9gGKhcAmpeqKEdhj.qRWCr4qoV1FU9se0Crx2hkMVNL2ktEW'
]

hashesGeneratedUsingBcryptModule = hashesGeneratedUsingBcryptModule.map(hash => bcrypt.compareAsync(string,hash))
hashesGeneratedUsingAspirineDotOrg = hashesGeneratedUsingAspirineDotOrg.map(hash => bcrypt.compareAsync(string,hash))
hashesGeneratedUsingAspirineDotOrgSwippedYForA = hashesGeneratedUsingAspirineDotOrgSwippedYForA.map(hash => bcrypt.compareAsync(string,hash))

Promise.all(hashesGeneratedUsingBcryptModule)
.tap(() => console.log('hashesGeneratedUsingBcryptModule'))
.then(console.log)

Promise.all(hashesGeneratedUsingAspirineDotOrg)
.tap(() => console.log('hashesGeneratedUsingAspirineDotOrg'))
.then(console.log)

Promise.all(hashesGeneratedUsingAspirineDotOrgSwippedYForA)
.tap(() => console.log('hashesGeneratedUsingAspirineDotOrgSwippedYForA'))
.then(console.log)

结果如下：

// hashesGeneratedUsingAspirineDotOrg
// [ false,false ]
// hashesGeneratedUsingBcryptModule
// [ true,true,true ]
// hashesGeneratedUsingAspirineDotOrgSwippedYForA
// [ false,false ]

我对如何在节点中比较$2y哈希感到难过.

有another Stack Overflow question / answer表示你可以将$2y改为$2a,但对我来说仍然失败.

更新！

我正在使用the generator 错误,因为它是.htpasswd密码生成器,您必须以此格式输入用户名和密码.

reggi helloworld

输出对应于此：

reggi:$2y$10$iuC7GYH/h1Gl1aDmcpLFpeJXN9OZXZUYnaqD2NnGLQiVGQYBDtbtO

在我放入之前

helloword

我假设哈希是一个空字符串.

通过这些更改,将y更改为a在bcrypt中工作.而双胞胎正好适用.

@H_403_49@解决方法

>使用bcrypt时,将y更改为a.
>当使用twin-bcrypt时,哈希就可以了.

使用http://aspirine.org/htpasswd_en.html时,请确保提供用户名和密码.

reggi helloworld

然后：

reggi:$2y$10$Am0Nf/B6.S/Wkpr6IVdIZeuHWNa/fqoLyTNmlyrSg22AjRf2vS.T.

这是一个包含bcrypt和twin-bcrypt的工作示例.

var twinBcrypt = require('twin-bcrypt')
var bcrypt = require('bcrypt')

var string = 'helloworld'

var bcryptAttempt = bcrypt.compareSync(string,"$2y$10$Am0Nf/B6.S/Wkpr6IVdIZeuHWNa/fqoLyTNmlyrSg22AjRf2vS.T.".replace(/^\$2y/,"$2a"))
console.log(bcryptAttempt)

var twinBcryptAttempt = twinBcrypt.compareSync(string,"$2y$10$Am0Nf/B6.S/Wkpr6IVdIZeuHWNa/fqoLyTNmlyrSg22AjRf2vS.T.")
console.log(twinBcryptAttempt)

输出：

true
true
