Silverlight MD5 implementation

I want to encrypt my passwords by using MD5. I searched on google and tried a few things, but it seems like they don't work with me...

I'm using the using System.Security.Cryptography library. That's what most of the people use apparently. I have this library, but when I want to use:

 MD5 m开发者_JAVA百科d5Hasher = MD5.Create();

it gives me an error...

Has anybody have some experience with MD5 in Silverlight

Help is welcome! :)

Thanks

First of all, MD5 is a hash algorithm, not an encryption algorithm...

If you really need to use the MD5 algorithm, I don't have any solution for you. However, if you want to use the SHA256 hash alogorithm, which is better than the MD5, then here's a code sample:

Public Function Hash(ByVal stringToHash As String) As String

    Dim returnValue As String = ""
    Dim unicodeEncoding As New System.Text.UnicodeEncoding
    Dim bytesToHash() As Byte
    Dim hashAlgorithm As System.Security.Cryptography.HashAlgorithm
    Dim hashBytes() As Byte

    'Get the bytes to hash
    If String.IsNullOrEmpty(stringToHash) Then
        bytesToHash = unicodeEncoding.GetBytes("")
    Else
        bytesToHash = unicodeEncoding.GetBytes(stringToHash)
    End If

    'Get the hashAlgorithm
    hashAlgorithm = New System.Security.Cryptography.SHA256Managed

    'Hash the bytes and convert it to string
    hashBytes = hashAlgorithm.ComputeHash(bytesToHash)
    returnValue = Convert.ToBase64String(hashBytes)

    Return returnValue

End Function
