Nothing wrong what you did here, but since you used the new style switch 
elsewhere, you could do:

return switch(mode) {
    case MODE_SIGN -> {
            paddingCopy = padding.pad(buffer, 0, bufOfs);
            if (paddingCopy == null) {
                throw new BadPaddingException("Padding error in signing");
            }
            yield RSACore.rsa(paddingCopy, privateKey, true);
     }

... and so on...
