07:28
How can companies store passwords safely and keep them away from hackers? Well let's find out! With all the data breaches lately, it's likely that the password of one of your accounts has been compromised. Hackers now might know the password you've used, but they also might not.. To understand why, we'll take a look at what methods a company can use to protect user passwords. We'll take a look at encryption, hash functions and a multilayer approach! 📚 Sources Can be found on my website: https://savjee.be/videos/simply-explained/hash-functions/ 🌍 Social Twitter: https://twitter.com/savjee Facebook: https://www.facebook.com/savjee ✏️ Check out my blog https://www.savjee.be

How secure is 256 bit security?
 
05:06
Supplement to the cryptocurrency video: How hard is it to find a 256-bit hash just by guessing and checking? What kind of computer would that take? Cryptocurrency video: https://youtu.be/bBC-nXj3Ng4 Thread for Q&A questions: http://3b1b.co/questions Several people have commented about how 2^256 would be the maximum number of attempts, not the average. This depends on the thing being attempted. If it's guessing a private key, you are correct, but for something like guessing which input to a hash function gives a desired output (as in bitcoin mining, for example), which is the kind of thing I had in mind here, 2^256 would indeed be the average number of attempts needed, at least for a true cryptographic hash function. Think of rolling a die until you get a 6, how many rolls do you need to make, on average?

Hashing Passwords | Node Authentication Tutorial – Part 3

🚀Support Chris Courses with Patreon: https://www.patreon.com/chriscourses 🖥Professional Web Development Services from Chris: https://resovere.com/ Learn the basics behind hashing users' passwords and why it is so very important to do this within any password related app. When it comes to securing your users' passwords, it's integral, no, absolutely necessary to hash your users' passwords before storing them in a database. Hashing is the process of scrambling up a user's password into a long string of characters that's undecipherable. The interesting thing about hashing: once you put the password in the hasher, there's no way to convert it back to its original form (at least from a mathematical standpoint). This helps ensure that your users' passwords are unreadable in the off chance someone happens to stumble upon the data in your database. Code along with me as I demonstrate how to implement hashing functionality into our user based node app. bcrypt npm link: https://www.npmjs.com/package/bcrypt Video Git Repo (starts at part 1): ------------------------------------------------ https://github.com/christopher4lis/express-cc Node Authentication Process: ------------------------------------------ // Add our boilerplate // 1.x Git clone express-cc repo // 2.x Run yarn / npm install // Create a new user in the database // 1.x Create a form within a view // 2.x Create route that'll process the form's post request // 3.x Create a database connection using .env file // 4.x Grab form input and insert into database // 5.x Add express-validation package // 6.x Validate user input on backend // 7.x Validate user input on frontend // 8.x Hash our user's password // 9.x Store user in database // Login user (update user session, return auth cookie) // 1. Install passport // 2. Configure passport with local strategy // Protect routes and only permit entry with authorization cookie // Create logout button // Create login page Video Timeline: ----------------------------- 00:50 - Why storing passwords in plain text is bad 01:36 - What is hashing? 02:35 - How to hash our users' passwords 03:05 - What is bcrypt? 06:01 - What is a salt? 07:08 - Testing out our hashing implementation To be continued...

Tricks to hack hashed passwords
 
06:53
As we know, hash function/algorithm is used to generate digest/checksum of data. Hash function is not reversible. However, it can be hacked, and it is easy. In this video, I will use some websites to crack hashed passwords manually. You can see how easy to hack hashed passwords if hackers use powerful computer or clusters of computers to hack our passwords. They would crack millions every second. Do not assume your passwords are safe as long as they are hashed into non-reversible digests.

This is How Hackers Crack Passwords!
 
05:44
In this video, we'll see how hackers really crack passwords. This video is edited with Filmora video editor, get it here : https://goo.gl/RtmNC5 DISCLAIMER : This video is intended only to educate people about how hackers crack passwords, and how important the strength of the password is, when coming to security. If you are using a common password like test123456 which I used in the video, then the hacker will easily be able to know the plain text form of your password from the hash string. There is something known as Rainbow tables. These rainbow tables contain the password hashes of numerous commonly used passwords. So the hacker will be to do a simple search with the password hash that he has, and if the password hash exists in the rainbow table, then that means the password is successfully cracked, and we have the password in a plain text. Remember that rainbow tables contain the password hashes of only the passwords which are commonly used. As a reference, you can go to https://crackstation.net/ If the password is not a commonly used password, then there comes dictionary attack and brute force attack. In dictionary attack, you have a wordlist. A wordlist is nothing but a huge text file with loads of passwords. In this attack, the hacker writes a code which compares the password hash to be cracked, with the password hash of each and every password that exists in the wordlist. Now, this attack can be target-specific as well. which means we can build a wordlist targeting an individual provided that we know some basic details about him/her. In a brute force attack, each and every combination of letters ,symbols and numbers are converted into their hash forms, and are then compared with the hash to be cracked. This is a more expensive. A new technique called salting is introduced by security analysts to give hackers a hard time in cracking passwords. In this technique, a specific combination of characters are inserted at specific positions of the plain text password before hashing. Every company has its own salting algorithm, and they don’t make their salting algorithm public For example, kets say Facebook salting algorithm inserts the string f&2p at the beginning, after the third character, and at the end of the plain text password. After salting the password, the salted password is then hashed by a hashing algorithm. So when salting is used, rainbow tables are of no use even if the password to be cracked is a weak commonly used password. Because the hashe of the password without salting do not match the hash of the password which is salted Also, brute force and dictionary attack are not effective to crack salted passwords unless the hacker already knows the salting algorithm employed by a company.

Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Cryptography: Crash Course Computer Science #33
 
12:33
Today we’re going to talk about how to keep information secret, and this isn’t a new goal. From as early as Julius Caesar’s Caesar cipher to Mary, Queen of Scots, encrypted messages to kill Queen Elizabeth in 1587, theres has long been a need to encrypt and decrypt private correspondence. This proved especially critical during World War II as Allan Turing and his team at Bletchley Park attempted to decrypt messages from Nazi Enigma machines, and this need has only grown as more and more information sensitive tasks are completed on our computers. So today, we’re going to walk you through some common encryption techniques such as the Advanced Encryption Standard (AES), Diffie-Hellman Key Exchange, and RSA which are employed to keep your information safe, private, and secure. Note: In October of 2017, researchers released a viable hack against WPA2, known as KRACK Attack, which uses AES to ensure secure communication between computers and network routers. The problem isn't with AES, which is provably secure, but with the communication protocol between router and computer. In order to set up secure communication, the computer and router have to agree through what's called a "handshake". If this handshake is interrupted in just the right way, an attacker can cause the handshake to fault to an insecure state and reveal critical information which makes the connection insecure. As is often the case with these situations, the problem is with an implementation, not the secure algorithm itself.

Password Best Practices
 
10:44
http://CustomSoftwareAdvisor.com/ Transcript below ... Storing passwords in a secure manner is extremely important. This video is a brief overview for the executive, project manager, or IT manager, of current best practices for secure password storage. -- Transcript -- 00:19 you may believe user credentials are stored in the database in clear text (http://bit.ly/lPqS3C), but this is a very naive way to store passwords. And for my career, it has been considered a very poor practice. 01:12 the problem is that if anybody hacks your database, they can easily log in as any user and do anything in the name of that user. 01:28 Even if your application doesn't allow users to do anything 'destructive', it can still serve as an embarrassment to the application and your company. 01:43 if you ever see user credentials stored in clear text format, you need to have a serious discussion with your programmer, about storing them in a secure manner. 02:00 Part of the solution is to mask the password. So instead of storing it in clear text, you would instead store the 'hash'. 02:16 what is a hash? A hash is the result of a computational algorithm (http://bit.ly/l5fdWa), where you pass in a password, and it returns a series of alpha numeric characters. 02:35 a hash cannot be reverse engineered to get the original input (i.e. the password). 02:44 a hash is a one way algorithm. In other words, you cannot take the result of a hashing algorithm and reverse it to get the original password; a hash result is similar to a scrambled egg, in that it can never be unscrambled. 03:05 However, the hashing algorithm is consistent, so hashing our password 'abc123', you get the same hash value every time. 03:21 don't create your own hashing algorithm, there are many included in most standard programming libraries. There are even hashing generators online (http://bit.ly/kFeGEM, http://bit.ly/jfpWRO, etc..). Notice when you enter my example password 'abc123' is hashed to '6367c48dd193d56ea7b0baad25b19455e529f5ee'. Notice also that both generators hash to the same values, proving the algorithms consistency. 04:08 however hashing isn't enough. You can't just store the password hash to be secure. 04:20 you can't just store the passwords hash, because hackers have databases called 'Rainbow Tables' (http://bit.ly/kXEnZV) where they can compare your hashed password and get the users password almost instantly. 05:25 [I stutter and did not edit so people would see how I really speak] 05:34 we can get around this problem by salting the password and hash the salted password. 05:49 what is a salt? A salt is a series of random alpha-numeric characters which are prepended (or appended) to the clear text password. Then the combination of salt + password is hashed. 06:16 Then the salt and hashed, salted, password is stored in the database along with the user name. 06:48 where do you get the salt? Again, there is functionality included in most programming libraries to generate this for you easily. 07:25 so how does this all tie together? When a user creates a new account, entering their user name and password (in clear test), then hits the submit button, we generate a salt, prepend/append the salt to the user entered clear text password, creating a 'salted password', then hash the salted password. Then the user name, salt, and the hash of the salted password, are all stored in the database. 08:11 When the user logs in, we retrieve the user credentials (salt and password hash) from the database based on their entered user name. Then we salt the user entered clear text password, using the salt from the database, and generate the hash on that salted password. We then compare the calculated hash against the hash stored in the database, and we know if the password is correct if the hash values match. If they don't match, then the password was incorrect. 09:08 in a nutshell, if you open your database and are able to read a user's password, then you need to get that fixed. It's a simple procedure, most programmers know how to do this, and there is plenty of documentation outlining how to secure your passwords.
