Error Installing Cimbalino

[rickwaugh1]

Trying to install this in Visual Studio 2012. I need the extensions for us of MD5. I get the following error:

You are trying to install this package into a project that targets 'portable-win+net45+wp80', Attempting to resolve dependency 'Cimbalino.Phone.Toolkit.Background (≥ 3.2.3)'.

As the error states, the Cimbalino.Phone.Toolkit package is not compatible with portable-win+net45+wp80 PCL projects.

But you're in luck, as last week I released the first beta version of Cimbalino.Toolkit.Portable (source code here), so please try with it instead.

We are having a lot of trouble getting this to work. All that we want is the MD5 hashing capability. We have added WP8 toolkit, WP8 toolkit.background, and toolkit.portable. Still having some grief - do we need to add more than that? It keeps telling us that Nuget packages are missing, but when Visual Studio to add missing packages, then rerun it, we still have the same problem.

This is driving us crazy, not being able to get this to work.

Rick, none of the 2 versions of the Cimbalino toolkit have a PCL implementation of the MD5 hashing algorithm.

However, you can solve this by creating a custom IMd5Provider interface in your PCL!

Let's say you have this type in your PCL project:

public class MyAwesomeClass
{
    public MyAwesomeClass()
    {
    }
}

Now just create the IMd5Interface and set it as a requirement to build the PCL class, like so:

public interface IMd5Interface
{
    byte[] CalculateMd5(byte[] data);
}

public class MyAwesomeClass
{
    private readonly IMd5Provider md5Provider;

    public MyAwesomeClass(IMd5Provider md5Provider)
    {
        _md5Provider = md5Provider;
    }
}

Then, on each of your projects that will use the PCL, create an implementation of that interface and inject an instance of it in your PCL type that will require calculating an MD5 hash.

To create the implementation, you can just add the Cimbalino.Phone.Background and use the Extension Methods that will add the MD5 calculation stuff!

Does this make sense to you?

Heh. I'm not the strongest C# coder in the world, but my team lead is. I'll talk to him.

It's crazy that Microsoft took the crytopgraphy package out. We have a client for whom we have to hash a string to send as part of a URL. That's it. And it's been tough getting anything to work.

We have implemented some of this, but we are not getting the results, sadly. We are using the WP8 toolkit and ByteArrayExtensions.cs. We followed these instructions:

|var myString= "this is my string data";

var myStringBytes= myString.GetBytes(); // this will get the UTF8 bytes for the string

var md5Hash= myStringBytes.ComputeMD5Hash().ToBase64String();|

Which we found at: http://stackoverflow.com/questions/15405628/i-want-to-use-md5-class-to-do-some-encryption-work-but-i-cant-find-it

We have two lines of code:

var inputBytes = inStr.GetBytes();**

var md5Hash = inputBytes.ComputeMD5Hash().ToBase64String();

This results in the following:

Original Value (inStr): vfvasq6lw9lvv8nbdesmondffs123abc1403310093yeyvp2g869akh62f

We get this in md5Hash: lqePhO+hIweEcuZ1lDDjwQ==

But it should be: 96a78f84efa123078472e6759430e3c1

Do you have any ideas as to what we are doing wrong? We have tried a few different conversions, different encoding, with no love.

The output format you are showing me is not Base64 string, but the Hexadecimal values of each byte! Something like this should do the job:

var retVal = inputBytes.ComputeMD5Hash();
var sb = new StringBuilder();
for (int i = 0; i < retVal.Length; i++)
{
    sb.Append(retVal[i].ToString("x2"));
}
var hash = sb.ToString();

[rickwaugh1]

There we go, that works great. Thanks so much, Pedro.

No problem, glad to be of help! :)
