How easy is it to break my hash? Posted: 21 Feb 2018 11:02 PM PST 22/2/18: Made mistake, its actually a potential one-way function not a hash So I decided to make a very simple one-way function which I could do without a computer. As far as I can see, the hash is collision less and somewhat hard to detect a pattern. The I was hoping r/crypto could find more vulnerabilities. It'd be impressed if you could find the input of 73740945964519364892687222629632 Here's everything you need to know about the You can test out the function and see it written in some popular languages here.

XTS-AES-128 w/256 bit key vs AES-256 Posted: 21 Feb 2018 03:51 PM PST Hey all. Simple question that I can't find the answer to. How does XTS-AES-128 w/ 256-bit key compare to AES-256 bit standard? [link] [comments] |
ELI5: How would quantum computers defeat modern encryption? Posted: 21 Feb 2018 09:50 AM PST How does the quantum computer decrypt compared to modern decryption? How can it be so much faster etc? [link] [comments] |
Posted: 21 Feb 2018 07:16 AM PST So, I'm creating this file encryption tool with Node. It's looking good, but I've realised that when I try to encrypt the folder names I get really long strings (IV:hex). [link] [comments] |
Unique signature scheme to use as a basis for Verifiable Random Functions? Posted: 21 Feb 2018 11:48 AM PST In the cryptocurrency paper "Algorand", Micali builds on a primitive: verifiable random functions, which are in turn built upon unique digital signatures. He doesn't specify what particular unique signature scheme he intends us to use. Now, I only know about two unique signature schemes: RSA-DSA, and BLS. Unfortunately, I've heard that BLS has had some vulnerabilities discovered recently. I've also recently asked on this subreddit about whether or not RSA is still a viable choice and the answer I got back was basically "it's really hard to get right, because there are so many attacks." So my question is: are there any other unique signature schemes that are ... uh... more robust? [link] [comments] |
