如何在Swift中将字符串哈希到SHA512？

Question

我正在构建一个社交媒体应用程序,我想帮助在Swift中将密码字符串编码为SHA512.我在GitHub上找到了CryptoSwift库,但我很难将它加载到我的Swift项目中并将其链接到我的项目文件.有谁知道如何相对容易地完成这个？先谢谢你,凯尔

Answer 1

Swift 3的解决方案:

extension String {

    func sha512() -> String {
        let data = self.data(using: .utf8)!
        var digest = [UInt8](repeating: 0, count: Int(CC_SHA512_DIGEST_LENGTH))
        data.withUnsafeBytes({
            _ = CC_SHA512($0, CC_LONG(data.count), &digest)
        })
        return digest.map({ String(format: "%02hhx", $0) }).joined(separator: "")
    }

}

func sha512() -> String {
    let data = self.data(using: .utf8)!
    var digest = [UInt8](repeating: 0, count: Int(CC_SHA512_DIGEST_LENGTH))
    data.withUnsafeBytes({
        _ = CC_SHA512($0, CC_LONG(data.count), &digest)
    })

    return digest.map({ String(format: "%02hhx", $0) }).joined(separator: "")
}

func sha512() -> String {
    let data = self.dataUsingEncoding(NSUTF8StringEncoding)!
    var digest = [UInt8](count:Int(CC_SHA512_DIGEST_LENGTH), repeatedValue: 0)
    CC_SHA512(data.bytes, CC_LONG(data.length), &digest)
    let hexBytes = digest.map { String(format: "%02hhx", $0) }

    return hexBytes.joinWithSeparator("")
}
