One solution could be setting up cronjobs to lock/unlock the game directory. To do so follow the steps below. Make sure cron-daemon is installed sudo apt-get install cron Prepare the game directory to be owned by root (alter the paths to fit your situation) sudo chown -v root:root ~/GameDirectory sudo chmod -v u+rwx ~/GameDirectory sudo chmod -v ...

First and foremost, I believe there isn't any encryption which can be deemed 100% secure. The reason for that is, it is human made. Despite that the evolution of hardware in the past 20 years has prooven that nothing is secure forever. Best example is here the long time deemed secure md5 one way encryption. But back to your question, your best security is ...

You can use vipe to edit pipelines: SYNOPSIS command1 | vipe | command2 DESCRIPTION vipe allows you to run your editor in the middle of a unix pipeline and edit the data that is being piped between programs. Your editor will have the full data being piped from command1 loaded into it, and when you save, that data will be ...

The easiest and most fail safe way will be to save your files in password protected archive files, 'zip' being the most popular archive file format supporting such protection. This format is supported directly in most OS's including Ubuntu and Windows, without installing any other applications. If you want complete drive encryption you'll have to install a ...

I want to remove the decryption... I want to decrypt my drive so that i don't have to use dislocker tool every time I need to access my drive. Kind of like turning off bitlocker permanently. That's similar to re-formatting any drive with a new filesystem, but to keep the files there are a few more steps: Copy the files somewhere else (in this ...

The processor uses dedicated instruction set. It is possible because of it, AES-NI. It enables fast encryption and decryption or you can say it cuts the overhead. It is fast because it is hardware implementation, as explained here. You can check about performance impacts here and they are worth it for added security.

How does AES / Rijndael Encryption in general work? This page has a fun A Stick Figure Guide to the Advanced Encryption Standard (AES) that looks easy to understand, though it looks to be 50+ images, for example these two: and It's far too much to duplicate it all here, but if you have to have an all-in-one image it's this one: Or, there's a ...

This will be a bit of a simplification, but I'll try to go through the process of accessing a file on an encrypted filesystem. For example, let's say a the beginning of the encrypted filesystem there's a file table; let's say we want to read /foo.bar. So, the first thing we do is read the beginning of the partition, decrypt it, and look through it for the ...

The software you are mentioning isn't safer than the one built into Ubuntu. No need to purchase anything special. The software you are talking about uses "256-bit AES encryption" according to their website. You can have an encryption using the same algorithm using the "cryptsetup" on Ubuntu with a regular thumb drive, see for example: ...

What else you should know about encrypting your home folder is that the data in it is not accessible when you are not logged in. If you have some automated or external process (like a crontab) that tries to access this data, it will work great while you are watching it, but fail when you are not watching it. This is very frustrating to debug.

That is working as intended. If you want to set a password using the useradd command, you are supposed to give a hashed version of the password to useradd. So if you provide your plain text password when the system validates that user's login it will fail since the stored password would not be the hashes version of the password you would expect it to have. ...

I just ran into the same issue. What had happened is that the key was stored in the old format: cat /etc/ssh/ssh_host_rsa_key SSH PRIVATE KEY FILE FORMAT 1.1 <encoded private key here> However the newer sshd is expecting the newer base64 encoded keys. cat /etc/ssh/ssh_host_rsa_key -----BEGIN RSA PRIVATE KEY----- <base64 encoding here> ...

Support for resizing LUKS partitions is being added right now to KDE Partition Manager. Grow support is already done in unreleased git versions and shrinking will be added soon. It will probably take a while until it reaches distributions and in particular Ubuntu but it will work at some point. Growing and shrinking LUKS in action: ...

As long as you ensure that non of the data on the encrypted partition is needed to enable a system boot you could just remove the reference to it from /etc/crypttab to stop it from being auto-mounted at boot. Alternatively you could leave the reference in place but add the noauto option. As for the swap the easiest solution here is just to have it be ...

There's a package in Ubuntu called ecryptfs which will give you a nice portable encryption option for your USB stick. The following is a snippet from the ubuntu server guide ecryptfs tutorial Using eCryptfs First, install the necessary packages. From a terminal prompt enter: sudo apt-get install ecryptfs-utils Now mount the partition to be encrypted: ...

There are several options, encrypt just some files with eCryptfs or EncFS, or a whole partition or drive with dm-crypt/LUKS (very similar to TrueCrypt, in fact cryptsetup can open (most?) TrueCrypt devices). See archlinux's informative wiki about disk encryption. LUKS encrypts entire partitions/drives, and should be installed by default on recent ...

Right-- snaps need to include all of their dependencies, so for instance the ownCloud snap bundles its own Apache, its own MySQL, etc. This is doable, but it's something you'd have to support in the snap that bundles the web server.
