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

Five* non-cryptographic hash functions enter. One hash function leaves.
Adam Harvey https://linux.conf.au/schedule/30208/view_talk When you say “hash function” in a room full of developers, people tend to think of the classics: MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-OHGODPLEASESTOP, and the like — cryptographic hash functions intended for cryptographic uses. There’s another world out there, though: non-cryptographic hashes. Sometimes you just need to figure out if you’ve already seen a string or structure. Sometimes you need a basic checksum. Sometimes you need a hash that’s just fast and can fit into a 32 bit integer. I’ll run through the state of the art in the world of non-cryptographic hashing — what your best options are, how they compare in terms of CPU and memory usage, and how they work. Who takes it? Whose mixing function reigns supreme? Let’s find out. * I’m saying “five”, but realistically I’m going to cover as many modern options as I can fit into the time available. Let’s say “five plus or minus two” in reality.
Hash Tables and Hash Functions
This video describes the fundamental principles of the hash table data structure which allows for very fast insertion and retrieval of data. It covers commonly used hash algorithms for numeric and alphanumeric keys and summarises the objectives of a good hash function. Collision resolution is described, including open addressing techniques such as linear and quadratic probing, and closed addressing techniques such as chaining with a linked list.

What is a crytographically secure hash function?
Modern cryptography depends on the existence of several special kinds of mathematical functions. One important kind is a one-way function. One-way functions are easy to compute but very hard for anyone to invert. Sometimes we refer to these functions as hash functions and their output as a hash. Cryptographic hash functions are a subset of hash functions that have special properties important to their use in cryptography.

Cipher Block Chaining (CBC) | Algorithm Modes in Cryptography
In this network security video tutorial we will study and understand the working of Cipher Block Chaining (CBC) also known as CBC algorithm mode. Cipher Block Chaining (CBC) - 1. Chaining adds a feedback mechanism to a block cipher 2. The results of the encryption of the previous block are fed back into the encryption of the current block. 3. In the first step; the first block of plain text and a random block of text, called Initialization Vector (IV) is used. 4. The IV has no special meaning it is simply used to make each message unique. 5. The value of IV is generated randomly.
