-    Funnction to prepare submission zip with specified version.
-
-    Version should be either r3 or r4.
-
-    For the current version on PQC hackerthon:
-    - ML-KEM composites are taken from the IPD version;
-    - Pure KEM for both IPD and non-IPD are kept;
-    - SLH algorithms are only available in non-IPD.
-
-    Essentially the submission contains:
-    - Pure KEM for both ipd (oid = 1.3.xxx) and non-ipd (oid = 2.16.xxx)
-    - ML-KEM composites from ipd
-    - SLH from non-ipd
-
+    Function to prepare submission zip with r4 certificates.
+    Contains only the der format certificates.
