Hash String MD5 using C#

md5.cs

private string GetMD5Hash(string input)
{
    System.Security.Cryptography.MD5 md5 = System.Security.Cryptography.MD5.Create();
    byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
    byte[] hash = md5.ComputeHash(inputBytes);
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < hash.Length; i++)
    {
        sb.Append(hash[i].ToString("x2"));
    }
    return sb.ToString();
}

private bool VerifyMd5Hash(string input, string hash)
{
    string hashOfInput = GetMD5Hash(input);
    StringComparer comparer = StringComparer.OrdinalIgnoreCase;
    return (0 == comparer.Compare(hashOfInput, hash)) ? true : false;
}

untuk merubah hasilnya menjadi Upper Case tinggal dirubah di baris 9 sb.Append(hash[i].ToString("x2")); dirubah menjadi sb.Append(hash[i].ToString("X2"));
