Help with Java Programming Assignment: Where and How to Get It

 

Java assignment help is something all students need. It’s not free if it’s high-quality, but you get valuable experience and priceless help during the hardest time. Before getting programming homework help, you should research the market and find a service that won’t disappoint.

It might be a bit time-consuming, but after this guide, you’ll definitely understand what qualities to look for. Some of the best programming, algebra, math, etc. helper websites are alike. For instance, homework help from assigncode.com is proven to be one of the most efficient for modern students. The specialists working there provide answers and solutions for all kinds of assignments.

To get the best website, you should know what to look for and how to do it. Let us guide you through the process step by step.

What to Look for in an Assignment Help Online Service

Here’s a list of qualities to look for:

Different levels.
Unless it’s a specialized service (only middle school, only college, only dissertations, etc.), a good website should provide many opportunities. To increase the number of customers and overall authority, it should offer papers from middle/high school to PhDs.

Guarantees and Policies.
An official, reliable service will have detailed policies about the privacy of your personal data, the use of the website, refunds, etc. There will also be guarantees of the quality of results you’ll be getting, writers’ professionalism in the subject and academic writing, samples authenticity, and more. It’s wise reading all of the additional pages before using a service.

Easy-to-use interface.
A trustworthy website like AssignCode.com should have a user-friendly interface. Anyone should be able to use it in the most efficient way. If there’s a problem with it, you can either change a browser or contact customer support for an answer to your question.

Effective customer support.
Customer support is the lens through which you can see the attitude of the business to its customers. If there’s a Live Chat, the operators are professional and friendly, and you get quick, clear replies, the website is considered a great and competitive one.

Reviews online.
Students often write reviews, describing their experience with a certain service. If it’s a new company, there might be only a few reviews, though. Making them one of your key reference points is a good idea. Read both positive and negative reviews, don’t focus on one kind.

Samples (free or paid).
A great assignment service should provide sample works by their writers, either for extra pay during the order or for free. You should see the style and quality of the programming the specialists provide. Doing so, you’re increasing the chances for a higher grade and the quality of your future apps.

Support at all stages.
From ideas to results, the service should have some kind of support integrated into every step of your consideration, order, waiting, and paying. Find a place where you won’t need to worry about the result, where quick replies and convenience are common, and even waiting for the final paper is fun.

Convenient payment options.
See what payment options you’re offered and if you can use any of them. There should be credit cards and digital payment services like PayPal. They are secure and very popular so that everyone can use them, all around the world.

A lot of students don’t know what to expect from a high-quality help app or website. That’s why you should remember that all the things above have to be present. Don’t opt for a low-quality service that only asks for money. You can find someone better to do my assignment. There’s much more trust in online sites now than before, but you should still be aware of scammers.

If the terms of cooperation seem too good or you can’t understand what you’re reading, it’s better to turn to a more professional service like AssignCode.com.

How to Find a Decent College Assignment Help Service

When a kid asks someone to do my assignment for me, he or she should be sure of the result. To go to the lesson feeling confident about your assignment, you can hire a tutor or get an additional course. But nothing does more last-minute damage-control than a trustworthy writing service.

Here’s an easy algorithm for finding one:

Go online and type “Java assignment help online”, “do my Java homework”, or a similar key phrase;

Go through the first page of the services offered by Google or the search engine of your choice;

Choose the services you like and put them on a list (you can leave all of them and even get other services by going to the second page);

Investigate each website, read their policies, find out what they offer and guarantee, look for your subject on the available list, levels of writing, etc.;

Gather up questions and contact customer support teams for answers (optional);

Find reviews online; read all of them and see if there are any pitfalls to be aware of;

Compare prices and see what services fit your budget the best;

Narrow down the list during the investigation process until you’re left with 1-3 leaders;

Choose one service at a time or, if you have more than one assignment, use all websites you’re left with;

Compare the results.

This easy guide will help you find the best Java programming help service. It’s better to have a couple of them as backups to one another. Sometimes services close for maintenance for some time, or the results might not be 100% what you need. Please, make sure you find out everything necessary about a service before using it. Falling for scammers once may make it easy to trust any online service again.

But this is the future, and you should be a part of it. Make sure to ask for help when you need it, and use only professional, reliable companies’ services. They will help you get to the top of the class!

Shodan a Search Engine for Hackers (Beginner Tutorial)

Many people have described Shodan as a search engine for hackers, and have even called it "the world's most dangerous search engine". It was developed by John Matherly in 2009, and unlike other search engines, it looks for specific information that can be invaluable to hackers. John Matherly is an Inernet Cartographer, hence the shodan.

Shodan is a type of search engine that allows users to search for Internet-connected devices and explicit website information such as the type of software running on a particular system and local anonymous FTP servers. Shodan can be used much in the same way as Google, but indexes information based on banner content, which is meta-data that servers send back to hosting clients. For the best results, Shodan searches should be executed using a series of filters in a string format.

So in conclusion we can say that, Shodan is a search engine for finding specific devices, and device types, that exist online. It is like an internet map that lets us see which device is connected to which or ports are open on a specific device or what operating system a certain system is using, etc. Rather than to locate specific content on a particular search term, SHODAN is designed to help the user find specific nodes (desktops, servers, routers, switches, etc.) with specific content in their banners.

What Shodan can do?

Shodan pulls service banners from servers and devices on the web, mostly port 80, but also ports 21 (ftp), 22 (SSH), 23 (telnet), 161 (SNMP), and 5060 (SIP). Since almost every new device now has a web interface (maybe even your refrigerator) to ease remote management, we can access innumerable web-enabled servers, network devices, home security systems, etc. Shodan can find us webcams, traffic signals, video projectors, routers, home heating systems, and SCADA systems that, for instance, control nuclear power plants and electrical grids. If it has a web interface, Shodan can find it! Although many of these systems communicate over port 80 using HTTP, many use telnet or other protocols over other ports. Keep that in mind when trying to connect to them.

How to use Shodan?

Understanding shodan is very important at first you might find it complex but once yu get to know it you will find it very handy in use and  very resourcefull too. So, now let us learn how to work with fasinating search engine. To use shodan to your advantage you have to first register to it.

Follow the steps to register. After registration a link will be sent to your e-mail ID for your activation of account on Shodan. Once your account is activated login to Shodan and now that you are logged in you are free to search anything.

Here are some examples for which you can use shodan to search up the things you want.

Webcam

When you search for webcam, it will show you all the webcam present in the world. It will show the results as shown in the image below :

Traffic Signals

Seaching about traffic signals or traffic signaks camera then it will show you all the traffic survallaince camera present.

Cisco

Searching about cisco will show you all the cisco routers in the world but you can search them by country. Like, here, i have found cisco routers in India and result is below image :

Scada

You can also search about Scada and you will get its information arround the whole world as shown :

netcam

Shodan can also show you about all the netcams in world and you can access them too with your hacking skills.

GPS

Shodan even lets you find all the GPS devices all over the world and for this you just have to type gps in the search box.

Port

Not only the devices but it can help find which port is open in which device. For example I have here searched port : 1723. Now we all know this port is used for VPN so through this we can know which device is using VPN as shown in image below :

When you search for port : 3389 it will show the operating system used by the device too which can be very useful.

This is how Shodan is useful for hackers as it gives all the information necessary to collect that too all over the world. And so you can manipulate this information as you desire.

Beginner Guide of Cryptography (Part 1)

Cryptography is conversion of plain readable text into unreadable form. In cryptography first the data is coverted into cipher text (that is encryption) and then the cipher text is coverted back into readable form (that is decryption). Cryptography basically works on the concept of encryption and decryption. Encryption and decryption should not be confused with encoding and decoding, in which data is converted from one form to another but is not deliberately altered so as to conceal its content. Encryption is achieved through the algorythms. These algorythms are works with logic, mathematic calculations and its complexities.

Encryption : Encrypted data is refered to cipher text. Cipher text is conversion of readable text into undreadable form. It is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. 

Decryption : Decryption is the process of converting encrypted data back into its original form, so it can be understood. To decrypt the data one needs a secret key or password so it can be decrypted.

Encryption can be done through three ways:

1. Symmetric

2. Asymmetric

3. Hash

Symmetric :Symmetric encryption’s job is to take readable data, scramble it to make it unreadable, then unscramble it again when it’s needed. It’s generally fast, and there are lots of good encryption methods to choose from.  The most important thing to remember about symmetric encryption is that both sides—the encrypter, and the decrypter—need access to the same key.

Asymmetric :Asymmetric encryption also takes readable data, scrambles it, and unscrambles it again at the other end, but there’s a twist : a different key is used for each end.  Encrypters use a public key to scramble the data, and decrypters use the matching private (secret) key on the other end to unscramble it again.

Hash :Hashing is what is actually happening when you hear about passwords being “encrypted”.  Strictly speaking, hashing is not a form of encryption, though it does use cryptography.  Hashing takes data and creates a hash out of it, a string of data with three important properties : the same data will always produce the same hash, it’s impossible to reverse it back to the original data, given knowledge of only the hash, it’s infeasible to create another string of data that will create the same hash (called a “collision” in crypto parlance). hash is to authenticate otherwise clearly-transmitted data using a shared secret (effectively, a key.) The hash is generated from the data and this secret, so that only the data and the hash are visible; the shared secret is not transmitted and it thus becomes infeasible to modify either the data or the hash without such modification being detected.

Now, there are very simple methods to achieve cryptography in our day to day life so that our data sharing can be done securely.

For Symmetric encyption we can simply visit the website : www.aesencryption.net , shown below : 

On this is website in first box writing your message and in second box give your password and then click on encrypt button on the right side.

The website will now reload itself and will provide you the encrypted text. Send this encrypted text to the desired person and tell them the key (which, in this case, is time).

The said person, after receiving your encrypted message, can come on this website to decrypt it. He/She wil simple have to copy the encrypted text and paste it on the first box and enter the key in next box and click on decrypt button on the right side as shown below :

After clicking on decrypt the site will reload itself and will provide you with plain text.

Hence, symetric encryption.

For Asymmetric encryption, we can simply go to www.igolder.com/pgp/generate-key/ , the following website wil open:

Click on generate PGP keys, after opening the website. A public and private key will be generated.

Now, copy the public key and click on PGP encrypt message option, it will redirect to the following page

Paste the public key in the first box and write your message in the second box. By clicking on Encrypt Message, you will get your message ecrypted.

Now, copy this encrypted message to the desired person along with the private key which you generated in the first step. The same person can also visited this site and click on PGP decrypt message option to decrypt the message. After clicking on the said option, the following page will open:

He/She can copy the private key and ecrypted message and paste it on first and second box respectively.

At last click on Decrypt message and your message will be decrypted.

Android Reverse Engineering : See Source Code of Android Apps

I am going to discuss how we can see the source code of the android apps and may be modify/hack according to our own convenience. Various attackers use this technique to inject their own malicious code in the app and the again compiling it and spreading the app.

Tools Required

·         Dex2jar: It is a tool which is used when working with android .dex and java .jar files.

·         Jd-gui: This tool opens up the entire coding of .apk file.

You can Download both these tools from here.

https://www.dropbox.com/s/4bv9lagfc09hg47/Dex2jar%20and%20jd0gui.rar

In this article I will be taking example of faceniff.apk, but you can take any app of your choice.

Steps involved in reverse engineering android app:

Change the extension of android app to "faceniff.apk.zip".

 Unzip the file using any unzipping software.

 Now open the command prompt and type "cd \".

 Then type "cd c:\android\dex2jar-0.0.9.7". (Here "C:\android\dex2jar-0.0.9.7" is the path of          dex2jar tool in my drive, this may be different for you). Press enter.

 Now type "dex2jar c:\android\Faceniff\classes.dex". Here "c:\android\Faceniff\classes.dex" is the path of the classes.dex file which your will surely be in the extracted folder of the android app.

 You will notice a new executable jar file in the unzipped folder of app. Now open that app with "jd.gui" and you will be able to see the source code of android app.
