This means that hashes unique and one-way can be used as a type of digital fingerprint for content. When you send an email, for example, you can hash the entire email and send the hash as well. Then the recipient can run the received message through the same hash function to check if the message has been tampered with in transit.
Also, passwords are usually hashed when they're stored. When a user enters their password, the computer computes the hash value and compares it to the stored hash value. If a hash can take data of any length or content, there are unlimited possibilities for data which can be hashed. Since a hash converts this text into a fixed length content for example, 32 characters , there are a finite number of combinations for a hash.
It is a very very large number of possibilities, but not an infinite one. Eventually two different sets of data will yield the same hash value. This is called a collision. If you have one hash and you're trying to go through every single possible plaintext value to find the plaintext which matches your hash, it will be a very long, very difficult process.
This is called the ' birthday problem ' in mathematics. The same type of analysis can be applied to hash functions in order to find any two hashes which match instead of a specific hash which matches the other. To avoid this, you can use longer hash functions such as SHA3, where the possibility of collisions is lower. You can try to brute force hashes, but it takes a very long time. The faster way to do that, is to use pre-computed rainbow tables which are similar to dictionary attacks.
The most important thing to remember about hacking is that no one wants to do more work than they have to do. For example, brute forcing hashes can be extremely time consuming and difficult.
If there's an easier way to get your password, that's probably what a nefarious actor will try first. That means that enabling basic cyber security best practices is probably the easiest way to prevent getting hacked. In fact, Microsoft recently reported that just enabling 2FA will end up blocking Popular password cracking tools. If you read this far, tweet to the author to show them you care.

Don't think about yourself as the best of the best. Make this your goal: you must become better and better. Every day that you didn't learn something new is a wasted day. You are all that counts. Become best, at any cost. There are no half-ways. You must give fully of yourself. As Yoda would say, "Do or do not.
There is no try. There is a major difference between a hacker and a cracker. A cracker is motivated by malicious namely: earning money reasons, while hackers attempt to retrieve information and gain knowledge through exploration - "bypassing security".
Don't delete entire logfiles. Instead, just remove only the incriminating entries from the file. The other question is, is there a backup log file? What if they just look for differences and find the exact things you erased? Always think about your actions. The best thing is to delete random lines of the log, including yours.

Step First of all, you need to go to the Minspy sign up page to create your new account. By entering your username and password, you will register yourself. Do not forget your username and password and make a note of them somewhere. Step Now, since the target is an Android device, download the Minspy Android solution. It will take not more than five minutes to download as it is a very lightweight app. During downloading, provide all the permissions to the app to ensure its proper working.
Technically, this is impossible for Android devices. Hence, it is advisable to keep a distance from those fraudulent apps that claim to do so. They can misuse your precious data. Step After completing the setup access, physical access to the target device is not required.
Just type your password and username on the control panel that you created in the initial steps. You will now be able to see all incoming and outgoing Facebook messages.
All media files that are sent or received will also be visible. Minspy not only tracks Facebook messages but also see the contact information for all incoming and outgoing messages. You can easily trace the contact details. All messages will provide timestamps with them. Apart from the messages, you can access all photographs and videos, even the deleted and exchanged ones.
By checking out the Minspy live demo , you can see the functions of the app without downloading it. It is perhaps the way to see if this is the right app for your needs. The most amazing thing about Minspy is that it uses cutting-edge stealth technology. Using this technology, the app works discreetly in the background and maintains your privacy.
This is very important and a must for spy apps, in fact! Did you know that after installation, the Minspy app icon is automatically deleted and the app works discreetly without draining the battery of the device? This is because a rapidly draining battery can raise suspicions among the target user. The other important feature of the Minspy app is its low memory usage.
Is it not surprising that this app consumes less than 2M space on an Android device that is almost negligible. The other spy apps usually consume more than ten times space in comparison to the Minspy app.
This again reduces the app burden on the system and does not slow down the target device. As we just saw, using this wonderful tool, you can easily hack a Facebook account and see the messages exchanged.
Let us now learn about the advanced keylogger technology. The keylogger tool is a unique hidden spy tool that stays on the target device.
When the target user presses the keys, each of these is then logged by the keylogger. Whenever the users enter the username and password of the Facebook account on their devices, this tool logs the data. The information is further sent remotely to you. Using this amazing feature of Minspy, you can hack the password and account credentials not only of Facebook but of other social media accounts and emails as well. Thus, by entering those credentials, you can see all the activities of the concerned account.
This provides you with full access over the target Facebook account. What if the target device runs the iOS operating system?
