Passwords & hash functions (Simply Explained)
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

Tricks to hack hashed passwords
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.

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...

Python Hash-Decrypter Program | Decode Hash Encryption 🔐
Hello Friends, In This Video, I'm Gonna Show You How You Can Encrypt & Decrypt The Hash String With The Help Of Hashlib Python Module Python-Hash-Cracker Program - https://goo.gl/zs3ikD HASHING : - If you need secure hashes or message digest algorithms, then Python’s standard library has you covered in the hashlib module. It includes the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 as well as RSA’s MD5 algorithm. Python also supports the adler32 and crc32 hash functions, but those are in the zlib module. One of the most popular uses of hashes is storing the hash of a password instead of the password itself. Of course, the hash has to be a good one or it can be decrypted. Another popular use case for hashes is to hash a file and then send the file and its hash separately. Then the person receiving the file can run a hash on the file to see if it matches the hash that was sent. If it does, then that means no one has changed the file in transit Cryptographic hashes are used in day-day life like in digital signatures, message authentication codes, manipulation detection, fingerprints, checksums (message integrity check), hash tables, password storage and much more. They are also used in sending messages over a network for security or storing messages in databases. There are many hash functions defined in the “hashlib” library in python. Some of the most used hash functions are: MD5: Message digest algorithm producing a 128 bit hash value. This is widely used to check data integrity. It is not suitable for use in other fields due to the security vulnerabilities of MD5. SHA: Group of algorithms designed by the U.S's NSA that are part of the U.S Federal Information processing standard. These algorithms are used widely in several cryptographic applications. The message length ranges from 160 bits to 512 bits. Functions associated : encode() : Converts the string into bytes to be acceptable by hash function. digest() : Returns the encoded data in byte format. hexdigest() : Returns the encoded data in hexadecimal format. ----------------------------------------------------------------------------------------------------------- Hope This Video Is Helpful For You ► Connect with me! ◄ Facebook - http://bit.ly/2tbOg3b Google+ - http://bit.ly/2jrWz6g Instagram - http://bit.ly/2tbR14z Reddit - https://bit.ly/2J5Vqfm ★★★Watch my most recent videos playlist★★★ Kali Linux - https://goo.gl/36M3JD Deep Web - https://goo.gl/7ueKNh Python Coding - https://goo.gl/dCtyrS Java Coding - https://goo.gl/oxFo8W Basic Computer - https://goo.gl/kwFXM3 Hacking - https://goo.gl/vjT916 Games Benchmark - https://goo.gl/eshw3T Gaming - https://goo.gl/mLuQwf Notepad Tricks -https://goo.gl/3uapMJ CMD Tricks - https://goo.gl/x1KH8C Facebook Tricks - https://goo.gl/1JV9Fz Problem Solved - https://goo.gl/eJwjXq Gmail Tricks - https://goo.gl/fSpbaB And talking about subscribing, please subscribe to my channel, if you enjoyed this video and want more how-to, Thanks so much for watching!

What is a collision ? What is preimage resistance ? What is second preimage resistance ? What are preimage and second preimage attacks ? How collision differs from second preimage attacks. Is sha-1 really broken ? Is MD5 really broken ? Is there any known preimage or second preimage attack against known hash like MD5 or SHA-1 or others. Why you should not use these hash for passwords. Can you use SHA-1 for passwords hashing in your website. How was shatter attack actually done. What is chosen prefix attack collision attack. Many such questions answered in this video. Very important video when cryptography is concerned. #collision #preimage #resistance #hash
