Как написать Java-функцию кода VB.net

Question

Как мне преобразовать эту функцию SHA512 в Java?

 Public Function Hash512(ByVal password As String, ByVal salt As String) As String
        Dim convertedToBytes As Byte() = Encoding.UTF8.GetBytes(password & salt)
        Dim hashType As HashAlgorithm = New SHA512Managed()
        Dim hashBytes As Byte() = hashType.ComputeHash(convertedToBytes)
        Dim hashedResult As String = Convert.ToBase64String(hashBytes)
        Return hashedResult
    End Function
