yescrypt

3 114 3.4 C

Password-based key derivation function and password hashing scheme building upon scrypt

Project mention: Inception: Leaking the root hash from /etc./shadow on AMD Zen 4 [video] | news.ycombinator.com | 2023-08-08

when you look properly at the end of the video the root hash starts with $y$ implying its yescrypt
more info here https://manpages.debian.org/unstable/libcrypt-dev/crypt.5.en...
https://www.openwall.com/yescrypt/
once you have the hash you have to use some rainbow tables if they exist for that hash function or bruteforce it
the authors of yescrypt claim: "Technically, yescrypt is the most scalable password hashing scheme so far, providing near-optimal security from offline password cracking across the whole range from kilobytes to terabytes and beyond. "
in any way, this is a local attack, someone / some software on your local machine would need to execute it so i am not overly stressed, password hashes leak all the time from all different sources
yet, it does worry me because my AMD stock is dropping on value because of this today :D

Project mention: How do crypto functions deal with the issue of character size? (e.g. Unicode) | /r/cryptography | 2023-06-18

Hey guys. If you remember me from several months ago, with this object de art, I am here with a less cringy question than that of 'I made a hash function!!!111'. I apologize if this question is basic btw. My question is, how do crypto functions, of any kind, deal with character size? For example in C, wchar_t is either 2 or 4 bytes. So, if the implementation goes through the stream like stream++ it will be stepping word-wise not byte-wise. And then if another machine, using a different implementation, reads the stream byte-wise and not word-wise, then it won't get the same message right?
