How to make some file that contains crucial data protected? For instance, suppose I have some files that are important, is there any method or strategy to make these kind of file more protected on Ubuntu? I even want to make some files ask for a password whenever someone tries to open it. Does it affect the version of Ubuntu in terms of security policy? May I use any encryption algorithm externally? Regards.

Is there a way to do full disk encryption after the install?  I have Ubuntu 11.10 installed with /home encrypted but really need the whole drive encrypted.  I would really like to do that with out a re-install.  Is there anyway to do that?

I have my cert.pem and cert.key files in /etc/apache2/ssl folders.  What would be the most secure permissions and ownership of:   /etc/apache2/ssl directory /etc/apache2/ssl/cert.pem file /etc/apache2/ssl/cert.key file    (Ensuring https:// access works of course :).  Thanks,  JP

I've been a Windows power user/administrator and professional tech for years, I just made the decision to go Linux, and wow, what a difference.     Is there any decently easy way to encrypt external volumes (i.e. USB keys, external hard drives, memory sticks, etc.) that works under Ubuntu 14.04?

I have the following file:  ---------- 1 Steve Steve 341 2017-12-21 01:51 myFile.txt   I switched the user to root in the terminal, and I have noticed the following behaviors:   I can read this file and write to it. I can't execute this file. If I set the x bit in the user permissions (---x------) or the group permissions (------x---) or the others permissions (---------x) of the file, then I would be able to execute this file.   Can anyone explain to me or point me to a tutorial that explains all of the rules that apply when the root user is dealing with files and directories?

I had installed Cryptkeeper in Ubuntu 16.04 lts. I have upgraded Ubuntu 16.04 to 18.04. After I upgraded to Ubuntu 18.04 , I completely lost my file which were encrypted through Cryptkeeper in Ubuntu 16.04. There are only folders where I kept my files. Now when I try to install Cryptkeeper in Ubuntu 18.04 through terminal it says  E: Package 'cryptkeeper' has no installation candidate   Does anyone know how to bring back my files without degrading Ubuntu to 16.04 LTS? Or, does anyone know of another file encryption program, as easy to install and use as Cryptkeeper, that will work reliably on Ubuntu 18.04 ?

I am lazy at home and use password authentication for my home machines. I am ready to move to key based authentication. There are many options on the web on how to do this, including catting then sshing the key over, scping the key over directly, etc.  I am looking for the easiest and recommended way to copy a key over, hopefully there is a convenience wrapper somewhere in the Ubuntu ssh package?  I'm already aware on .

I accidentally moved all folders from root to a subfolder. (/bin, /etc, /home, /lib, /usr... all moved) The only ones that were not moved, since they were in use, are  /bak, /boot, /dev, /proc, /sys.  Now, any command that I try to execute will simply not happen. I constantly get "No such file or directory".  I am connected through ssh and through ftp, but I cannot move files through ftp, as direct SU login is disabled. I also have access to the actual server if I need to do something directly from there.  I'm assuming I would need to edit a configuration file in order to tell it where to find the /bin folder and that would help me get access again, but I don't know which file that would be or how to do it (since I can't even run chmod to change permissions).  Is there any way out of this other than re-installing?  I am working on an old version of CentOS.  I'm extremely new to the world of Linux, hence this action and the question...

I have a new Ubuntu 10.04 installation with encrypted home directory (using the built-in encryption offered by Ubuntu installer).   What's the easiest way to stop using encryption? (I.e., to decrypt my home directory permanently.)   (It's giving me problems with kernel updates, and I'd just like to cut down on all the hassle I'm having with this installation.)

I would like to encrypt my hard drive so that it requires a password to access it. However features like BitLocker in Windows will only work under Windows, and cannot be accessed from another OS such as  Ubuntu or Mac OS X.  How can I create a cross-platform encrypted file system?

I'm using Linux (centos) machine, I already connected to the other system using ssh. Now my question is how can I copy files from one system to another system?  Suppose, in my environment, I have two system like System A and System B. I'm using System A machine and some other using System B machine.  How can I copy a file from System B to System A? And, copy a file from System A to System B?

I can't do ssh public key login to my server and I think this issue is related to the fact my home is encrypted. I chose the option "encrypt my home folder" under the Ubuntu install setup. The permissions on /home/MY-USER are 700.  I've tried another workstation and everything works fine. I would be glad if someone help me to get out this without removing the encryption.

How to set custom keyboard shortcuts from terminal for different Linux versions?  Basically I want to know where Linux stores the keyboard shortcut files and how it can be edited.  On my research I found a file ~/.config/compiz-1/compizconfig but it was more or like encrypted when I tried to open it with nano.

At what point during the installation of Ubuntu 18.04 do I get the option to encrypt my disk?  Somehow I missed it, so if I'll need to start over I'd like to know where to look.  Alternatively, what is a good way to encrypt after installation? I was looking at  but the link to  is broken.  Update: I had also started looking into alternatives to encrypt home folder only but I'll follow the discussion from  for that.

I am creating an ZIP file with ZipFile in Python 2.5, it works ok so far:  import zipfile, os  locfile = "test.txt" loczip = os.path.splitext (locfile)[0] + ".zip" zip = zipfile.ZipFile (loczip, "w") zip.write (locfile) zip.close()   but I couldn't find how to encrypt the files in the ZIP file. I could use system and call PKZIP -s, but I suppose there must be a more "Pythonic" way.  I'm looking for an open source solution.
