Do websites store passwords or hashes?
Taking this into account, where do websites actually store passwords? Typically, websites use hash functions in order to convert a user’s inputted password to a safe format for storing.
How are passwords stored on a website?
As discussed in that earlier article, websites do not (or, rather, should not), keep a record of your password. Instead, they “hash” the string of characters you provide as your password, and store that hash instead. When you log in, they hash the password you type in and compare the result with the hash they stored.
Why are passwords should be hashed « Stack Exchange Security blog?
The hashing process is like a meat grinder: there is no key, everybody can operate it, but there is no way to get your cow back in full moo-ing state. Whereas encryption would be akin to locking the cow in a stable. Cryptographic hash functions are functions which anybody can compute, efficiently, over arbitrary inputs.
Which is the best tool to hash passwords?
A hash function is the right tool for that. In full details, the hashing process should include a per-password random salt (stored along the hashed value) and be appropriately slow (through thousands or millions of nested iterations), but that’s not the subject of this post. Just use bcrypt.
Which is the correct term for hashing passwords?
Cryptographic hash functions are functions which anybody can compute, efficiently, over arbitrary inputs. They are deterministic (same input yields same output, for everybody). In shorter words: if MD5 or SHA-1 is involved, this is password hashing, not password encryption. Let’s use the correct term.
How to pass password hashes to John the Ripper?
John the Ripper does not understand how to parse .rar files (that’s what rar2john is for); you need to pass the file containing the extracted password hash: Thanks for contributing an answer to Information Security Stack Exchange!
