A one liner method for MD5 Hashing / performance / verbose approach?

MD5AsExtension.cs

public static string ToMD5(this string input)
{
	//comment about this
    var sb = new System.Text.StringBuilder();
    
	//comment about that
	var md5 = System.Security.Cryptography.MD5.Create();
	var bytesFromInput = System.Text.Encoding.Unicode.GetBytes(input);
	var hashedBytes = md5.ComputeHash(bytesFromInput);
	
	foreach (var byt in hashedBytes)
    {
		//To Hexa comment blah
        sb.Append(byt.ToString("X2"));
    }
    return sb.ToString();
}

MD5OneLiner.cs

public static string CalculateMd5Hash(string input)
{
    return string.Join("",
                           System.Security.Cryptography.MD5.Create()
                                .ComputeHash(System.Text.Encoding.Unicode.GetBytes(input))
                                    .Select(byt => byt.ToString("X2")));
}

MD5OneLinerBetterPerhaps.cs

public static string CalculateMd5HashBetterPerhaps(string input)
{
    var sb = new System.Text.StringBuilder();
    foreach (var byt in System.Security.Cryptography.MD5.Create()
                              .ComputeHash(System.Text.Encoding.Unicode.GetBytes(input)))
    {
        sb.Append(byt.ToString("X2"));
    }
    return sb.ToString();
}

Wow) thats so cool!
