how to create Hash SHA512 of a string in c #

[lingers]

i need a sample of Hash SHA512 with string value in c sharp for c sharp website

public static string Sha512Hash(string input)
{
    byte[] ba = Encoding.UTF8.GetBytes(input);
    SHA512Managed sha5 = new SHA512Managed();
    byte[] ba2 = sha5.ComputeHash(ba);
    sha5 = null;
    return BitConverter.ToString(ba2).Replace("-", string.E

mpty).ToLower();
}

Here is a method I use regularly to create a SHA512 of a string

 
 
public static string SHA512(string plainText, byte[] saltBytes)
        {
            if (saltBytes == null)
            {
                int minSalt = 4;
                int maxSalt = 8;
 
                rnd rnd = new rnd();
                int saltSize = rnd.Next(minSalt, maxSalt);
                saltBytes = new byte[saltSize];
                RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
                rng.GetNonZeroBytes(saltBytes);
            }
 
            byte[] bytes = Encoding.UTF8.GetBytes(plainText);
            byte[] textWithSaltBytes = new byte[bytes.Length + saltBytes.Length];
 
            for (int i = 0; i < bytes.Length; i++)
            {
                textWithSaltBytes[i] = bytes[i];
            }
 
            for (int i = 0; i < saltBytes.Length; i++)
            {
                textWithSaltBytes[bytes.Length + i] = saltBytes[i];
            }
 
            hshAlgorithm hsh;
            hsh = new SHA512Managed();
 
            byte[] hshBytes = hsh.Computehsh(textWithSaltBytes);
            byte[] hshWithSaltBytes = new byte[hshBytes.Length + saltBytes.Length];
 
            for (int i = 0; i < hshBytes.Length; i++)
            {
                hshWithSaltBytes[i] = hshBytes[i];
            }
 
            for (int i = 0; i < saltBytes.Length; i++)
            {
                hshWithSaltBytes[hshBytes.Length + i] = saltBytes[i];
            }
 
            string hshValue = Convert.ToBase64String(hshWithSaltBytes);
 
            return hshValue;
        }
