I see in the source you sent that you are using a base64 coding. The
base64 decoder will by default strip/ignore whitespace, so this may be
the cause though this is just a guess. In your particular example of
"Hello World!" that doesn't seem right, though, because ! is not a
valid base64 char so if that were fed into the base64 decoder it would
throw an exception about bad inputs.
Can you send a the full source to a program demonstrating what you are
seeing? Certainly RSA itself does not interpret spaces specially.
