Doesn't work with filenames that contain spaces

[tumatanquang]

I got an error:

Exception in thread "main" java.io.FileNotFoundException: D:\Simple%20Tools.jar (The system cannot find the file specified)
        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(ZipFile.java:220)
        at java.util.zip.ZipFile.<init>(ZipFile.java:150)
        at java.util.zip.ZipFile.<init>(ZipFile.java:164)
        at jcrypt.Main.main(Main.java:20)

Although before encryption, the tool still works normally even though the filename contains spaces.
Please update support for filenames containing spaces.
Thanks!
