>>24991>idk what hashes areNta, but essentially hashes are a fundamental security measure. Before hashes, passwords were just kept on servers and what not in plain text. This has two main concerns: A. if a malicious actor gains accsess to the site, the passwords are right there for exploitation and B: maybe I don't trust the person I'm sending my password to. Hence, encryption was introduced. At a very simple level, hashing just involves taking a given password (doesnt have to be a password but using this as an example) and processes it through a mathematical algorithm that rearranges and/or changes the password in such a way the output looks nothing alike to the original. Modern-day hashes do this mathematical algorithm hundreds of times over, for extra security.
<Back to how this matters to youWhen you scan a wifi network, such as using airdump, occasionally the wifi router will broadcast the wifi password as a hash. Otherwise, your phone wouldn't be able to connect. You can use airdump to find the hash, save it to a file, then simply upload the file to your computer, and using a software such as Hashcat, you can then crack it.
