使用ECB的iOS 3DES会返回一半正确的数据

使用3DES + ECBalgorithmencryption密码时出现问题。 这里是我使用的代码： class func encryptPassword(pass: String) -> String { let keyString = "123456789012345678901234" let keyData: NSData! = (keyString as NSString).dataUsingEncoding(NSUTF8StringEncoding) as NSData! let keyBytes = UnsafePointer<UInt8>(keyData.bytes) let data: NSData! = (pass as NSString).dataUsingEncoding(NSUTF8StringEncoding) as NSData! let dataLength = UInt(data.length) let dataBytes = UnsafePointer<UInt8>(data.bytes) var cryptData = NSMutableData(length: Int(dataLength) + kCCBlockSize3DES)! var cryptPointer = […]
