使用 swift 验证 md5 哈希密码

Question

我正在尝试从 Blob 中获取 NSData 对象以将其加载到 Web 视图中。我已阅读有关 SQLite.swift 的文档，但我不清楚。请帮我。我想我需要一个工作示例。

我的代码： https://gist.github.com/gobozgz/9d1b02364f878bc1a026

import UIKit
import SQLite
class AreaInfoViewController: UIViewController {
    @IBOutlet weak var webView: UIWebView!    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Here I Will load the webView PDFFile into the webView
        // webView.loadRequest(getAreaPdf())
        }

    func getAreaPdf () -> NSDATA {
        var myPdf:NSDATA // I think this is wrong

        let dirPaths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)
        let docsDir = dirPaths[0]
        let databasePath = docsDir.stringByAppendingString("/db.sqlite")
        let db = try! Connection(databasePath, readonly: true)

        let areas = Table("areas")
        let id = Expression<Int64>("id")
        let name = Expression<String>("name")
        let pdffile = Expression<SQLite.Blob>("pdffile")
        let query = areas.select(id,name,pdffile)
            .filter(id == 1)
            .limit(1)
        let result = db.prepare(query)
        for row in result {
            myPdf = row[pdffile] // Obviusly this is wrong
        }
        return myPdf // Obviusly this is wrong too
    }
}

我终于用 bcrypt 代替了 md5。我使用了 JKBCrypt 和 JKBCrypt.verifyPassword

因为我使用的是从 php 生成的哈希存储的密码，所以我不得不使用一些小技巧：

 var hash = user[password]
 let regex = try! NSRegularExpression(pattern: "\y\\$", options: .CaseInsensitive)
 hash = regex.stringByReplacingMatchesInString(hash, options: [], range: NSRange(0..<hash.utf16.count), withTemplate: "\a\\$")
 auth = JKBCrypt.verifyPassword(userPassword, matchesHash: hash)!
