Since that's the strategy, it doesn't really make passphrases any less secure since they're just going to attack a whole lot of accounts and get as much as they can. There will always be people with weak passphrases.

But nearly all passphrases are weak and that's why they're less secure. I've stated this several times now. In fact, did you even read the fucking link I provided?

The whole passphrase point is taken directly from professional security experts who specialise in cracking passwords and thus hardening systems against such attacks. But as usual, you know better.

I swear to God, sometimes chatting on here is like pulling teeth <_<


There's nothing stopping crackers from targeting password hash generators either.

You can't target hash generators for my method. the hash generator is only used as a method to create a random password. You could just as easily mash the keyboard for all the difference it makes. Except with my method you don't need to store the password anywhere.

You haven't the slightest idea what you're talking about, so I beg you, please, for the love of God, read the link I provided. Do yourself a favour and educate yourself on this subject because at the moment it's pretty clear that your understanding is outdated at best.

Why can't you target hash generators? After all, to generate your hash, you're basically using a passphrase and the website for the salt.

If passphrase cracking is as easy as you say it is, then it's just as easy for a cracker to figure out the passphrase you use to generate the hash.

I'd already answered that.

The method used to create the hash is irrelevant in this specific context. Whether you used a hash generator or randomly mashed the keys on the keyboard - the password is still a random character string and it's that password that you need to crack. Knowing the method used to create the password would, at most, only tell you which characters to include in your brute force attack (eg base64 encoded sha512 hashes will have 0-9. a-z, A-Z + and /. Where as another random character string could include different characters.

What you're thinking about is the storage of passwords in hashes - which is completely different.

If you store a password in a hash then you can use a hash table to match hash strings and effectively reverse engineer the originating password. But the password itself wouldn't be a hash. That password could be a passphrase or any other password that the user chose.

So using a hash as a password itself doesn't leave itself vulnerable to detection based on the hash generator used. Using such a generator is just an arbitrary method to produce an arbitrary random string.


If passphrase cracking is as easy as you say it is, then it's just as easy for a cracker to figure out the passphrase you use to generate the hash.

No, you're getting yourself completely muddled there.
The only possible way you could find out the passphrase for the hash used in my method would be if you found out the output password; and if they know that then they already have your password so there's no bloody point trying to find the passphrase used to generate that password as they already have your login details lol.

My method is little different to randomly mashing a keyboard in terms of the password generated. Except I provide a way to exactly repeat the random mashing in a secure way. However the attack would only ever have exposure to the end result so could not and would not care about the method used to create the password (ie whether it was random keyboard mashing, password generator or a hash generator).
