How to use Sha/hash in Xamarin

I want to hash a String with C# in Xamarin. Normally i use:

using System.Security.Cryptography;

public string SHA512StringHash(String input)
    SHA512 shaM = new SHA512Managed();
    // Convert the input string to a byte array and compute the hash.
    byte[] data = shaM.ComputeHash(Encoding.UTF8.GetBytes(input));
    // Create a new Stringbuilder to collect the bytes
    // and create a string.
    StringBuilder sBuilder = new StringBuilder();
    // Loop through each byte of the hashed data 
    // and format each one as a hexadecimal string.
    for (int i = 0; i < data.Length; i++)
    // Return the hexadecimal string.
    input = sBuilder.ToString();
    return (input);

But in Xamarin i seem not able to include this library. Now i was wondering, if there is a way to include this library or an alternitive to easily hash a Password.

    Sorry to bump this thread after so long, but I find myself having some problems implementing a method to hash sensible data.
    I'm trying @MichaelRumpler method, but as I don't have System.Security.Cryptography available, so I don't have Windows.Security.Cryptography available in my PCL.

    Or am I getting the answer wrong and the suggestion is to implement platform specific code to hash strings and call it through an interface?

    Use the dependency service and do the encryption in the platform specific project.
