          Dim bytes As Byte() = oEncoder.GetBytes(String2Hash)

          Dim myHash As Byte() = MD5Hasher.ComputeHash(bytes)
          Dim myCapacity As Integer = 7
          Dim sb As System.Text.StringBuilder = New System.Text.StringBuilder(myCapacity)
          Dim I As Integer

Solution 1

As Wes said, a hash only goes one way. You can't turn a hash back in to the starting string.
Of course, a 5.

Solution 2

Considering that MD5 is not an encryption algorithm, but is in fact a hash function (and a broken one at that), no there is no such thing as a decryptor for MD5.
Of course, a 5.
