在Swift应用程序中使用哈希密码 [英] Hash password in Swift application
问题描述
我的同事选择了scrypt哈希算法,长度为64字节,一个固定的种子,然后转换为十六进制。
HashingA12345678Z导致: 25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251
种子是 HeanpyftAkWilfUd 。
在服务器上,使用此实现: https://github.com/ricmoo/pyscrypt
示例:
scrypt.hash(A12345678Z,HeanpyftAkWilfUd)。encode('hex ')

我的问题是如何在Swift中做到这一点?使用什么库,如果可能的话 - 向我展示示例代码,这将导致哈希 A12345678Z 到这个:
25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251
a href =https://github.com/jedisct1/swift-sodium =nofollow> Swift-Sodium 。它是钠加密库的Swift界面。
以下是一个来自README.md的例子
let sodium = Sodium()!
让密码=正确的马电池装订.toData()!
let hashedStr = sodium.pwHash.scrypt.str(密码,
opsLimit:sodium.pwHash.scrypt.OpsLimitInteractive,
memLimit:sodium.pwHash.scrypt.MemLimitInteractive)!
如果sodium.pwHash.scrypt.strVerify(hashStr,passwd:password)== false {
//密码不匹配给定的散列字符串
}
For security purposes I will encrypt some data, including the user password in my application.
My colleagues have chosen scrypt hashing algorithm, for a 64 bytes length, with a fixed seed, then converted to hex.
Hashing "A12345678Z" leads to: 25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251
Seed is "HeanpyftAkWilfUd".
On server, they are using this implementation : https://github.com/ricmoo/pyscrypt
Example:
scrypt.hash("A12345678Z", "HeanpyftAkWilfUd").encode('hex’)
->
25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251
My question is how to do that in Swift? What library to use and if it possible - show me sample code, that will lead hashing "A12345678Z" to exactly this:
25fac84a1cc3a8f6706848d1016cfe7e9d3631691306dcacae68c11c7b54f0bf89e7a7fc51f7fcc19671775acb21c8d928c4c96bb66d915925de58b8b36ab251
You could use Swift-Sodium. It's a Swift interface for the Sodium crypto library.
Here's an example from the README.md
let sodium = Sodium()!
let password = "Correct Horse Battery Staple".toData()!
let hashedStr = sodium.pwHash.scrypt.str(password,
opsLimit: sodium.pwHash.scrypt.OpsLimitInteractive,
memLimit: sodium.pwHash.scrypt.MemLimitInteractive)!
if sodium.pwHash.scrypt.strVerify(hashStr, passwd: password) == false {
// Password doesn't match the given hash string
}
