Hybrid encryption

A method of encryption that combines two or more encryption schemes and includes a combination of symmetric and asymmetric encryption to take advantage of the strengths of each type of encryption

symmetric encryption

A type of encryption where the same key is used to encrypt and decrypt the message. This differs from asymmetric (or public-key) encryption, which uses one key to encrypt a message and another to decrypt the message.

DES

Short for Data Encryption Standard, a popular symmetric-key encryption method developed in 1975 and standardized by ANSI in 1981 as ANSI X.3.92. DES uses a 56-bit key and uses the blockcipher method, which breaks text into 64-bit blocks and then encrypts them

Symmetric-key cryptography

An encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message. Contrast this with public-key cryptology, which utilizes two keys - a public key to encrypt messages and a private key to decrypt them.

Symmetric-key systems are simpler and faster, but their main drawback is that the two parties must somehow exchange the key in a secure way. Public-key encryption avoids this problem because the public key can be distributed in a non-secure way, and the private key is never transmitted.

Symmetric-key cryptography is sometimes called secret-key cryptography. The most popular symmetric-key system is the Data Encryption Standard (DES).

cipher text

Data that has been encrypted. Cipher text is unreadable until it has been converted into plain text (decrypted) with a key.

Cryptography

The art of protecting information by transforming it (encrypting it) into an unreadable format, called cipher-text. Only those who possess a secret key can decipher (or decrypt) the message into plain text. Encrypted messages can sometimes be broken by cryptanalysis, also called codebreaking, although modern cryptography techniques are virtually unbreakable.

As the Internet and other forms of electronic communication become more prevalent, electronic security is becoming increasingly important. Cryptography is used to protect e-mail messages, credit card information, and corporate data. One of the most popular cryptography systems used on the Internet is Pretty Good Privacybecause it's effective and free.

Cryptography systems can be broadly classified into symmetric-key systems that use a single key that both the sender and recipient have, and public-keysystems that use two keys, a public key known to everyone and a private key that only the recipient of messages uses.

Hide your message inside the Image

Hello, i am going to show you how to hide your secret message inside the image.

You can also visit http://errorcode401.blogspot.in/2013/06/hide-file-inside-image-needed-things-1.html to hide your file inside the image.

Let's Start.

Step 1: Create Message File

Open Notepad [Start >> Run >> Type "notepad" >> Enter]
Type your message which you want to hide in image and save it on deaktop.
Here i am saving my message in msg.txt file.

Step 2: Select Image

Now you have to select image in which you want to hide your message.
Copy that Image File on desktop. [Here i am copying 401.jpg image]

Step 3: Hide Message in image

Now Open Command prompt [Start >> Run >> Type "cmd" >> Enter]
Now type cd desktop then hit Enter.
Then Type copy /b 401.jpg + msg.txt hiddenmsg.jpg then Enter.

[Note : Here hiddenmsg.jpg is new image file which contain your message.
401.jpg is your image and msg.txt is text file
you have to change this file name in command as per your file name]

Step 4: Done

Thats it...!!! Now you can delete your old file [401.jpg and msg.txt]
Now you can see one new image file on your desktop name with hiddenmsg,jpg

Step 5: How you can see your Message

When you want to see your message which is hidden in your Image then Open that new Image file [hiddenmsg.jpg] with notepad.

How to Hide Files Inside Pictures

In this Instructable, I will show you how to hide files inside a picture file. They are almost undetectable, and can be made very hard to get.

You will need these things:
1) A picture to hide stuff in
2) Files to be hidden
3) A file compression software (I use 7-zip, which you can get here)
4) Command Prompt

UPDATE
You can not only hide files in pictures, but music files, videos, and just about anything else.

Step 1: Compressing the Files

The first thing you will do is make a new folder on the C drive. I will call this folder "x". Inside this folder, place the files to be hidden and the picture that will hide everything. The picture that will hide everything in it cannot have any spaces in the name, so I called it "Picture".

Step 2: Making a Zipped File

You will now make a compressed file. THIS IS ESSENTIAL!

Open your file compression software, and navigate to the folder you made. Make the files that will be hidden into a zipped file, and name it something simple, like "x".

I now have, in the "x" folder, a picture named "Picture.png" and a compressed file called "x.7z".

Step 3: Using CMD

Open CMD by going to Start, All Programs, Accessories, Command Prompt orStart, Run, and type CMD. Type the following into the window that pops up:

cd\

Press enter. Then type:

cd x

Press enter. Now, type the following, substituting the appropriate file and/or foler names:

copy /b Picture.png + x.7z NEWPICTURE.png

This is what everything means that you have just typed:
cd\: This takes the cmd to the C Drive.
cd x: This takes the cmd to the "x" folder in the C Drive.
copy /b: This makes a binary copy of the files Picture.png and x.7z.

Where it says HIDDEN FILES.png, you should put the name of the new picture with the same extension as the other picture that was copied (my other picture was a .png, so my new one is a .png).

If you did it right, then you should have a new picture saved in the "x" folder with whatever name you gave it. You can delete the original files you wanted hidden now.

Step 4: All Finished

There. Now you have a picture that has files hidden inside it. The picture can still be opened, although I do not know if it can be taken and edited, like in Adobe Photoshop. If someone can find out, please leave a comment to tell me.

To extract the files you put in the picture, open up your compression software and select the picture with the files inside it and extract them. A new folder will be created with the same name as the picture, and it will contain the files you hid.

If you want to take files to school and give them to a friend, this is a great way to do that, as the administrators, or "techies" as I call them, will not be able to find those files. Also, you do not have to hide only pictures and videos; you can hide text files, programs, sound files, and much more. You just have to make sure that they are compressed.

The only way that someone can tell if there are files inside a picture is if:
1) You tell them
2) They notice that your innocent picture of a bunny happens to be 4MB.

Other than that, you will have some undetectable files that you can cart arround with you, where ever you go.

How To Repair Detectable But Corrupt USB Drive

Have you suddenly encountered with the problem that when you plug in your USB drive, the Removable media shows up but when you try to open it, it returns with the message “Please insert a disk in to drive H:”.

If yes then you have been on right tutorial page.

By applying this simple method you’ll have 80 % chance to get back your USB drive hardware.

This works only in the above error condition. If the windows doesn’t detect your USB drive, then there is probably flaw in the USB media.

Please keep in mind that, you’ll have to lose your data when following this tutorial.

Plug in your USB drive.

Go to Start>My Computer, right click on My Computer icon and click on Manage menu.

Computer Management window will pop up. Click on Disk management under Storage tree menu.

Now at the right side of the window right click on your removable media. (unlike the image below, it will show unknown information), right click on your removable media and choose Change Drive Letter and Paths.

Now in new window choose any drive later that is not taken by any media (M:, N: , :K: etc).

Click on ok button and close the management window. Try opening your pendirve. There may be the chance to have your pendrive recovered if this method worked.

If the problem still prevails then follow the above tutorial but instead of choosing  Change drive letter and paths, choose Fomrat and give a quick format to it.

Now you’ll have finally lost your data but the pendrive is safe in your hands.

Hope this tutorial was working. If it didn’t please do comment me. I’ll find other solutions as well.

Creating Emergency Shortcut To Shutdown Windows

This tutorial might be useful to those who hate to use mouse to shutdown windows. With the combination of three keys you can easily shutdown your computer. In this tutorial, I am going to show you, how you can create a shutdown shortcut key.

In desktop Right click>New>Shortcut

A create shortcut window will pop up. In the input field type, “shutdown –s” (without quotes), as shown in the figure. Remember that there is space between shutdown and -s

Click on next.

In next window, name anything you want your shortcut name to be. I named it shutdown.Alternatively you can have no name for shortcut. Deleting all the text and clicking on finish button won’t help you to create blank shortcut name.

To make blank shortcut name, Hold down ALT and type 0160 (i.e. ALT+0160). This will give a blank name. Click on finis button. You’ll have your name less shortcut menu ready.

Finally you’ll have shutdown shortcut icon similar to the image below:

Now all you need to is add shortcut keys to it. To do so, right click on the shortcut icon that you’ve just created. Choose properties.

By default shortcut key is set to none. Click on the shortcut key input field. Hold down CTRL and press any key you want. I used CTRL+ALT+S.  Windows allows only the combination of CTRL+ALT to have a shortcut.

Now you are finally done.

Click on OK.

To test, Press CTRL+ALT+S (or any shortcut that you’ve given), following window will popup.

Press enter and sit back and relax until your system shuts down.

Hope this tutorial was a great help.
