How can I SHA512 a string in C#?

public string SHA512(string input)
{
     string hash;

You might try these lines:

public static string GenSHA512(string s, bool l = false)
{
    string r = "";
    try
    {
        byte[] d = Encoding.UTF8.GetBytes(s);
        using (SHA512 a = new SHA512Managed())
        {
            byte[] h = a.ComputeHash(d);
            r = BitConverter.ToString(h).Replace("-", "");
        }
        r = (l ? r.ToLowerInvariant() : r);
    }
    catch
    {

    }
    return r;
}

1. It is disposed at the end
2. It's safe
3. Supports lower case
