Encrypt String to SHA256 without key

For a signature in an API connection I need to encode a string to SHA256 without using a key. Which method in APEX can I use for this?

String S = 'THIS IS AN EXAMPLE STRING';

If I encrupt this string to SHA256 via the following website I get a correct 64 character string without the use of a key:

Result = '2b970a5104771ac1890d755254e5ce9d2cc8e8d488961f241879e337fb8be502'

I cannot find a method in APEX that does the same.

The one that comes close is crypto.generateMac(algorithmName, input, privateKey) but this requires a key and Crypto.generateDigest(algorithmName, input) does not give a result that can be handled properly.
