Passwords & hash functions (Simply Explained)
 
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

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.

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.

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?
