Question

我正在玩Xcode游戏机中的REST API，我需要使用SHA1哈希。我找到的所有解决方案都依赖于Common Crypto，而且似乎并没有直接在Swift游乐场中提供。有没有办法在Swift游乐场中使用SHA1？

Answer 1

快速而肮脏的解决方案：

func SHA1HashString(string: String) -> String {
    let task = NSTask()
    task.launchPath = "/usr/bin/shasum"
    task.arguments = []

    let inputPipe = NSPipe()
    inputPipe.fileHandleForWriting.writeData(string.dataUsingEncoding(NSUTF8StringEncoding)!)
    inputPipe.fileHandleForWriting.closeFile()

    let outputPipe = NSPipe()
    task.standardOutput = outputPipe
    task.standardInput = inputPipe
    task.launch()

    let data = outputPipe.fileHandleForReading.readDataToEndOfFile()
    let hash = String(data: data, encoding: NSUTF8StringEncoding)!
    return hash.stringByReplacingOccurrencesOfString("  -\n", withString: "")
}

有一个CommonCrypto Swift包装器https://github.com/onmyway133/Arcane

你应该能够将它导入你的游乐场，因为有一个MacOS和iOS游乐场的例子在存储库中使用它。

Zoul的解决方案，移植到 Swift 3 ：

import Foundation 

func SHA1HashString(string: String) -> String {
let task = Process()
task.launchPath = "/usr/bin/shasum"
task.arguments = []

let inputPipe = Pipe()
inputPipe.fileHandleForWriting.write(string.data(using:String.Encoding.utf8)!)
inputPipe.fileHandleForWriting.closeFile()

let outputPipe = Pipe()
task.standardOutput = outputPipe
task.standardInput = inputPipe
task.launch()

let data = outputPipe.fileHandleForReading.readDataToEndOfFile()
let hash = String(data: data, encoding: String.Encoding.utf8)!
return hash.replacingOccurrences(of: "  -\n ", with: "")
}

注意：适用于Apple Swift version 3.0.2 (swiftlang-800.0.63 clang-800.0.42.1)的终端，但请参阅在Ubuntu上运行：Error: Use of unresolved Identifier 'Process'

有没有办法在Swift游乐场中使用Common Crypto？
