How to use a SHA256 MessageDigest in Java on Linux

I encountered a problem while trying to get my java project running on my Debian 10 server. Everything seems to work, but java throws an error when i try to get an instance of a MessageDigest with "SHA256".

It occurs in this line:

MessageDigest digest = MessageDigest.getInstance("SHA256");

The exception:

java.security.NoSuchAlgorithmException: SHA256 MessageDigest not available

Is there a way to install SHA256 functionality or another way i can create a sha256 hash?

MessageDigest.getInstance("SHA-256");

and to list all available:

Set<String> messageDigest = Security.getAlgorithms("MessageDigest");
messageDigest.forEach(System.out::println);
