Suggested January 2024 Use Encryptpad Text Editor To Edit And Encrypt Files In Ubuntu
At times we store some of our personal or sensitive information in the form of plain text on our laptops or pen drives in order to make it easily accessible whenever required. While that does offer convenience, it also poses a great risk – risk of the information getting misused in case the laptop or memory stick getting stolen/misplaced and landing in the wrong hands.
Encryption is one of the safest solutions to the aforementioned problem. While there are many tools available in the market that allow you to encrypt and decrypt information, wouldn’t it be even more convenient if there were a text editor that could double as an encryption/decryption tool as well? In this article we will discuss one such application, EncryptPad.
Note: all the instructions/commands explained in this article have been tested on Ubuntu 16.04 LTS.
EncryptPadEncryptPad is basically a normal text editor, but what makes it special is its ability to encrypt files. Not only plain text files, but you can also use it to encrypt and decrypt binary files kept on your disk. It’s an open source application that offers both graphical as well as command line interfaces.
Download and InstallOn Ubuntu you can easily download and install EncryptPad by running the following commands:
sudo
add-apt-repository ppa:nilarimogard/
webupd8sudo
apt update
sudo
apt
install
encryptpad encryptcliOf course, you can also install it from source; to download the latest version, head here.
Once the application is installed successfully, it can be launched from Ubuntu Dash.
UsageHere’s what the EncryptPad UI looks like:
As you can see, it’s a basic text editor UI with quick access icons for creating, opening, saving, and editing files. To start, let’s discuss how to password-protect a plain text file using the editor.
Hitting the “Save” button will bring up a Password box where you’ll be asked to enter a new password as well as confirm it.
This way you can protect a plain text file by encrypting it with a password.
This way you can protect a plain text file using a key file. To open a file with such protection, the editor will require both a key file as well as the password that protects it.
For more information on the editor, head to the tutorials section on the tool’s official website.
ConclusionThe biggest strength of EncryptPad is that it’s not difficult to use at all. This, coupled with the fact that the tool’s official website, offers detailed tutorials, makes it ideal for new users. If you were looking for such an application, I’d encourage you to give EncryptPad a shot.

How To Read Text Files Using Linecache In Python
Solution..
The linecache module implements cache which holds the contents of files, parsed into separate lines, in memory. linecache module returns line/s by indexing into a list, and saves time over repeatedly reading the file and parsing lines to find the one desired.
lincecache module is very useful when looking for multiple lines from the same file.
Prepare test data. You can get this text by just using Google and searching for sample text.

Linecache always includes the newline at the end of the line. Therefore, if the line is empty, the return value is just the newline.

The contents of the file are maintained in a cache, so be careful of memory consumption.
How To Use Google Docs? Create And Edit Presentations.
If you have not changed the default settings, the service will provide you with 20 presentation templates. So instead of creating a presentation from scratch, you can use any of them and save your time. They are quite simple, but most users should be happy with them. There is a business model, dark, bright, colorful, plain and patterned.
Toolbar
Like in other Google Docs modules, the toolbar is placed at the top of the editing window. It contains the most common tasks, commands and functions. At first blush, the red button rivets our attention. It lets you add new slides. But we can also do it by using the shortcut Ctrl + M.
Next to the red button, there is a small arrow which hides different types of slides under the hood. We are mostly interested in the Title and Content. It is the most commonly used slide with a header and a place to insert more text. If you are using a template, you will notice that the background differs a little bit from the one in the title’s page.
In addition to this, we recommend to try Title and Two columns (split text into two columns) and Empty, which give us more leeway to edit, but it lacks the background. Other buttons include the well-known Undo and Redo options and already described Copy formatting.
Text Boxes and AutoShapes
The presentation’s toolbar consists of a comprehensive set of functions. So we are not going to discuss all of its components. We will focus on the most important ones. One of them is a Text box. This command allows you to add new boxes for a text in any place you wish.
Next, we have other option letting users insert a variety of objects including pictures, shapes and lines. The Shapes and Lines can be used on their own which mean you can draw on your slides by pressing the left mouse button. You can also customize the inserted objects, for example you can change color, size, location, fill color or line color.
Animated transitions
In the bar, there are options which let you change the theme (template) of the presentation and the layout of the slide – if you think that the currently used theme no longer serves its purpose, and the other will look better. Above the bar, there is a File menu and Edit. Most of the stuff looks like the one in a word processor.
What’s new in the Presentation module is a Slide option that allows you to add new pages to the presentation, but also to change their order. The second important thing is the Arrange menu, which helps you organize your items within the slides. With this feature, we can perfectly center the title vertically or rotate it 90 degrees.
When talking about presentations, not only the content is important. Visual effects and animations play a vital role, since they make your presentation look more creative and professional. To access them, exit the editing mode and then the toolbar changes. At the end, there is a Transition option that opens sidebar full of graphics effects.
As usual, the Help menu provides a list of keyboard shortcuts concerning activities related to editing presentations.
Left sidebar
Unlike in other modules, apart from the edit box below the toolbar there is also a left sidebar with a list of your slides in the form of miniatures. It offers a convenient way to access various presentations – even the most extensive ones.
To see the results of your work, select the View the presentation option in the upper right corner of the screen. Down Arrow opens a menu of options. From this place, you can choose whether you want to display your presentation with notes or in a new window. Of course, the presentation is displayed in full screen.
Data transfer
While creating a presentation using Google Docs is simple and fun, the problem arises when you want to display it. Of course, we need access the Internet. If you go to a business meeting and want to show the results of your work, it is recommended to download the document to disk before the meeting rather than desperately look for Wi-Fi.
The presentation editor comes bundled with other functions which have already described, such as sharing. For detailed information, feel free to go to our previous articles concerning Google Documents. Next week, we will show you how to create forms and drawing in Google Docs.
How To Use Microsoft Editor In Word To Create Best Content? – Webnots

Readability Statistics
Note that some options in this Editor panel is only available in Windows version, we will explain the Windows Word version as a base for further explanation in this article.
1. Editor Score and Writing StyleBased on the quality of your document, Word will automatically calculate the score and show in the Editor. You need to have at least 100 words for Word to do this for you. The target score should be 100 which should be easier by fixing your mistakes in the document. Under the score, you will see the options to change your writing style. You can change the style to formal, professional, or casual and the Editor will recalculate the score accordingly.
Editor Score and Writing Style
The formal version will consider every aspect of the writing while other two options will ignore certain errors. For example, you will see a dotted blue line when you write “somewhat different” in formal writing while professional and casual styles will ignore this error. Make sure to select the correct style so that you will get appropriate suggestions.
2. CorrectionsSpelling Check in Word Editor
2. RefinementsHere, you can find suggestions related to clarity, conciseness, formality, inclusiveness, punctuation conventions, resume, sensitive geopolitical references, and vocabulary.

Fixing Errors from Editor InterfaceIf you do not have time to manually go through each item in your document, the best option is to quickly go through the Editor interface. It will show the consolidated errors with limited information, and you can replace the words with suggestion or ignore the check. However, we recommend you going through as explained above to learn proper writing style and improve your copy writing skills.
Note: sometime, you might have wrongly ignored a word from the Editor check. If you want to include the ignored words again, simply close and reopen the document and check the Editor again. The ignored words will appear again with suggestions in the Editor.
Final WordsMicrosoft Word Editor is a super useful tool powered by AI and anyone can write a professional copy with the help of this. Best part is that you can check the plagiarism within Word document and insert the references if required. If you really like Word Editor, it is also available as Chrome and Edge extensions. You can install these extensions and do free spelling and grammar checks in any content you write in the browser like emails, messages, etc.
How To Encrypt A Harddrive?
Most of us use a password on our computers, files, and folders to protect against unauthorized access. However, password protection does not guarantee the safety of data.
So, to prevent data theft, encrypting the hard drive is the best option. While Encryption also uses a password for protection, it adds up the security by scrambling all the data inside a file and changing them into cipher codes. So, even if someone finds the file, they won’t be able to make sense of the data without the encryption key.
You have several options to encrypt the hard drive, such as the built-in BitLocker or other third-party tools in Windows. Let’s discuss the stepwise process to add the encryption using both methods here.
BitLocker has been incorporated into Windows OS since the time of Windows Vista. It now has much-improved security algorithms.
When you lock your drive with BitLocker, it encrypts all the files, and you will require the security password or recovery key to decrypt and access those data. It employs an AES encryption type with 128 or 256-bit keys algorithm for protection.
Let’s move on to keep your drive encrypted using BitLocker.
Open Windows Explorer by pressing Windows + ‘E’.
Select Use a password to unlock the drive. It may not be usual for everyone to possess a Smart card.
Once the encryption completes, restart your PC.
If you do not find the Turn on BitLocker feature in the context menu of the drive (in the case of earlier Windows versions), you can do this through Control Panel.
Press Windows + ‘R’ and enter control to navigate to the Control Panel.
Select View by Small Icons.
Here onwards, follow the same instructions mentioned in and after Step 5 above.
You can also use several reliable third-party freeware applications that can encrypt your drive with the highest security if you do not find BitLocker secure. Some of them are TrueCrypt, AESCrypt, VeraCrypt, and so on.
Here, we are going to provide the steps to encrypt the drive using an open-source application, VeraCrypt, for demonstration.
To Encrypt Non-System Partition
Download the VeraCrypt Installer file and Install it accordingly on your system.
Run VeraCrypt on your PC.
Select Standard VeraCrypt volume or Hidden VeraCrypt volume by reading the information given there.
Select Yes in the confirmation window.
To Encrypt a System Partition
If you are trying to encrypt the drive containing the Operating System, the process is a little different.
Follow the same process up to step 3 mentioned above,
Choose the Encryption method and set Password.
Now continue according to the instruction mentioned earlier.
It will take seconds to a few minutes to complete the process. You cannot access the encrypted drive yet, as it is hidden and unmounted. So, to access the encrypted drive,
Run VeraCrypt again.
Choose a random unused Drive letter from the list.
Once you are free from security threats or you want to remove the encryption, you can easily decrypt the drive.
You can turn off the protection in the drive to decrypt it completely.
Open Control Panel and navigate to BitLocker Drive Encryption.
Enter the password or recovery key to unlock it.
The encryption will be removed from the drive.
