Quick password based file encryption with ccrypt.

Gnugpg is in many ways the champion of encryption on Linux(personal opinion).

Sometimes there is a need to do quick password based encryption. This can be achieved with ccrypt.

Ccrypt should be available on standard Debian/Ubuntu or Centos8 repository resources.

I use Debian base here, but the steps should be similar on Centos8 or equivalent.

sudo apt-get install ccrypt -y

echo “I am going to be encrypted” >> ./example.txt

ccrypt ./example.txt

At this point a password for the encryption is needed. For this example, I used: hello.

After the encryption, my file will be found as: example.txt.cpt.

If I now try to read this cpt file, there will be nothing that can be understood on the output.

To decrypt and make the file readable again: ccdecrypt ./example.txt.cpt

After decryption, the example.txt is again found as a clear text file.

QCalculator version 2 released.

Changes in this version:

Program’s outlook is redesigned.

Full Keypad/Keypress support is added.

Notice: Back key is Space. Return key is equals.

If your keys do not seem to work, click the display part of the calculator to remedy the issue.

Also make sure that you have numlock enabled if you are using a keypad.

The source code is available on the project’s Github page:

When nothing works, network connections gone on Windows 10 and how to fix it.

If you are unlucky, one day you will encounter a situation were your Windows 10 network seems to be completely gone without any prior warnings.

Here a steps to remedy this issue. All the steps should be done on safe-mode or safe-mode with networking. You can get to safe-mode by pressing either F7 or F8 directly after booting your machine.

Notice. While booting your computer into safe-mode with networking. Do not attach any network cable.

Symptoms of the issue:

All network cards are malfunctioning. They are either in a state of being disabled or status is “Windows is still trying to install software” or equivalent.

Solution:

Open regedit or command prompt and enable msiserver on safe-mode. When msiserver is enabled, you can proceed to uninstall/modify your software.

Command prompt version – Run these commands as an administrator on cmd. If you prever GUI use regedit and add similar entry via it.

REG ADD “HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\MSIServer” /VE /T REG_SZ /F /D “Service”

Next, open cmd as an administrator and execute:

net start msiserver

At this point proceed to uninstall software that might cause issues to Windows.

First, check if you have installed anything strange. Also, check if there are any new driver updates.

Remove anything that seems out of place or suspicious. If you have VirtualBox installed, consider removing it first. VirtualBox has sometimes caused trouble to Windows networking with its adapters.

At this point reboot your machine, and return to safe-mode.

If network is still stuck, check if you have any VPNs installed. Start removing your VPN installations one by one and reboot the machine after each VPN removal. There is a good change that some VPN you are were using prior to your issues, has malfunctioned and removing it will get your network connectivity working again.

Why do these things happen in the first place?

Usually network cards start malfunctioning when some Windows upgrade or driver upgrade goes wrong. These things can happen from time to time since the quality of software components and their drivers might vary. Usually these things are rare, so most of the Windows users should be safe from havoc.
