You may try the unlimited strength key policy files oracle.com/it/java/technologies/javase-jce8-downloads.html get the one for your Java version. — BigMike

Yes, IBMJava does have different policy files than Oracle/Open; it also has different cryptoproviders. The last time I managed to find useful files on (one of) the IBM website(s) was about 10 years ago, so I can't even suggest where to look :-( — dave_thompson_085
