Я хочу сделать шифрование Laravel в iOS Swift 3 .
Crypt::encrypt('123456'); Я пробовал что-то вроде этого, но это не работает. Я думаю, что в этом коде что-то не так:
func generateRandomBytes() -> String? { var keyData = Data(count: 10) let result = keyData.withUnsafeMutableBytes { (mutableBytes: UnsafeMutablePointer<UInt8>) -> Int32 in SecRandomCopyBytes(kSecRandomDefault, keyData.count, mutableBytes) } if result == errSecSuccess { return keyData.base64EncodedString() } else { print("Problem generating random bytes") return nil } } override func viewDidLoad() { super.viewDidLoad() let ivString:String = generateRandomBytes()! let ivDecodedData : Data = ivString.data(using: .utf8)! print("iv : ",ivString ,ivString.characters.count) let purePasswordString:String = "123456" let serialString = String(format:"s:%lu:\"%@\";",purePasswordString.characters.count,purePasswordString) let keyString = "u6KuXJLIUwEUl7noY8J8H1ffDRwLC/5gjaWW1qTQ3hE=" let encryptedStrKEYData = NSData(base64Encoded: keyString, options: .init(rawValue: 0))! let encryptedStrKEYDataString:String = NSString(data: encryptedStrKEYData as Data, encoding: String.Encoding.ascii.rawValue)! as String let keyData: Data = Data(base64Encoded: keyString)! let message = serialString let data: NSData! = (message as NSString).data(using: String.Encoding.ascii.rawValue) as NSData! let cryptData = NSMutableData(length: Int(data.length) + kCCBlockSizeAES128)! let keyLength = size_t(kCCKeySizeAES256) let operation: CCOperation = UInt32(kCCEncrypt) let algoritm: CCAlgorithm = UInt32(kCCAlgorithmAES128) let options: CCOptions = UInt32(kCCOptionPKCS7Padding) var numBytesEncrypted :size_t = 0 let cryptStatus = CCCrypt(operation, algoritm, options, keyData.bytes, keyLength, ivDecodedData.bytes, data.bytes, data.length, cryptData.mutableBytes, cryptData.length, &numBytesEncrypted) if UInt32(cryptStatus) == UInt32(kCCSuccess) { cryptData.length = Int(numBytesEncrypted) print("cryptLength = \(numBytesEncrypted), cryptData = \(cryptData)") let base64cryptString = cryptData.base64EncodedString(options: [.lineLength64Characters]) let mix:String = String(format:"%@%@",ivString,base64cryptString) let cKey = encryptedStrKEYDataString.cString(using: String.Encoding.utf8) let cData = mix.cString(using: String.Encoding.utf8) let algorithm = CCHmacAlgorithm(kCCHmacAlgSHA256) let size = Int(CC_SHA256_DIGEST_LENGTH) var result = [CUnsignedChar](repeating: 0, count: size ) CCHmac(algorithm, cKey!, Int(strlen(cKey!)), cData!, Int(strlen(cData!)), &result) let hmacData:NSData = NSData(bytes: result, length: size) let hmacBase64 = hmacData.base64EncodedString(options: []) let dict:Dictionary = ["iv":ivString,"value":base64cryptString,"mac":hmacBase64] do { let jsonData = try JSONSerialization.data(withJSONObject: dict, options: .init(rawValue: 0)) let j:String = jsonData.base64EncodedString() print("done: ", j , j.characters.count) } catch { print(error.localizedDescription) } } else { print("Error: \(cryptStatus)") } }
И посмотрите, как это поможет:

И это моя последняя попытка:
