I'd like to install/execute JCrypTool on my Ubuntu 14.04

How should I do it?

-- info from comment --

I am using jcryptool-0.9.9-linux.gtk.x86.tar.gz, I have extracted it to home directory, but it doesn't work. I attempt to do the following, but it results in error: 

artur@artur-Inspiron-3558:~$ sudo tar xzvf jcryptool-0.9.9-linux.gtk.x86.tar.gz 
[sudo] password for artur: 
tar (child): jcryptool-0.9.9-linux.gtk.x86.tar.gz: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now 
artur@artur-Inspiron-3558:~$

Am I doing something wrong?

PS:

Thank you for your support, though I still get problems with installing this program. Since it requires at least Java 8(and I have it), it gives some error related to JDK:

artur@artur-Inspiron-3558:~$ cd jcryptool
artur@artur-Inspiron-3558:~/jcryptool$ ./JCrypTool 
JCrypTool:

It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

What might be the problem?

There seems to be a known issue with the combination of Ubuntu 14.04, Eclipse 3.8 and Java 8.

This answer specifies:

Eclipse 3.8 doesn't seems to work with java 8.
So you need to install eclipse 4.2 (Luna) if you need to use Java 8. And I prefer to use Oracle Java rather than open jdk.

In order to Install/execute JCrypTool on Ubuntu 14.04 you need the following:

  • Install eclipse 4.2
  • Install Java 8
  • Download jcryptool-0.9.9 tar file, and tar xzvf in your preferred folder.

I've downloaded the 64 bit version (as my Ubuntu is 64 bit) of jcryptool-0.9.9-linux.gtk.x86_64.tar.gz from here.

I've opened it in my home directory using:

tar xzvf jcryptool-0.9.9-linux.gtk.x86_64.tar.gz

And run it using:

cd jcryptool
./JCrypTool

There is no need to install it in /usr (unless you would like to share it with other users, etc)
