Use a strong password, as my granddaughter does 3

I do write my passwords (sometimes), but as I stated before – I do it in other language, plus it is a description of the password, and not the password itself.
I had a secure key (I don’t have it any more) which had a password of 0546, so I wrote on it something like ‘less than’ (part of a lyric of a song many years ago), six minus one, two plus two, and five plus one – all in other language.
I keep written down other passwords like: the license plate of my car plus 55, or what I call my wife plus her age (she is, for example, 23 for last X years
)So in order to guess my passwords, you need to know something about me.
Have fun.

ages = a very long time...
the estimated time to crack said pswd:
55347407972105100000000000000000000 hrs.
for a single P4 machine...
where as IBM's Blue Gene could do it in just under:
3773258843786680000000000000 hrs.

I tend to use passwords that are a pseudo-acronym.
One example that I give when training is:
I like to eat cookies at night!
Take the first letter... substitute where you can...
I l 2 e c @ n !
A nice, easy-to-remember, but very strong password.
Just my 2¢

Ah - I think I've found the calculator you used. And I can generate a simlilar result to uypu by making some poor assumptions - such as that the password we are breaking is known to have 1 uppercase character and 31 lowercase alphas. But if we were brute forcing this for real we would no know that. We could perhaps at best assume the password is an unknown mix of upper and lowercase characters.
The calculator doesn't have a line for that, but the calculation is pretty simple:
52^32 possibilities ...
which at the test speeds used in the calculator (and accepting their simple averaging calculation to shrink the search space as valid) come out at:
237,715,307,158,561,000,000,000,000,000,000,000,000,000,000.00 hours
or
9,904,804,464,940,040,000,000,000,000,000,000,000,000,000 days
And even if we accept the calculators rather erroneous assumption that a supercomputer can carry out a comparison in each FLOP, the 2004 Blue Gene only reduces that to
673,796,222,104,765,000,000,000,000,000,000,000 days
whilst using the same (erroneous) assumptions 2010s Tianhe-IA supercomputer (currently fastest in the world) would reduce it to:
18,905,906,594,655,500,000,000,000,000,000,000 days
which is over 51 * 10^27 years ...

and so it is crackable... though we may never see the result, that does not negate the statement: "Bruteforce will eventually get that one...". But lets not nit-pick, it is a VERY VERY strong password, as most people cannot remember even 8 chars let alone 32... ;-)

AH! But it isn't nitpicking. In cryptography the length of time it would take to crack something is an important consideration into whether something is crackable or not. Something that would take this long is considered uncrackable.
I don't think 'ages' or 'difficult' really conveyed this ...

However due to the world of "cloud" (I hate that term) computing, these times are being massily reduced. What was "uncrackable" a few years ago, falls in hours / minutes these days. It's a question of finance these days.

You may want to investigate how massive 'massily' actually needs to be before we can consider this particular example crackable via brute force ... (which is not to say that alternative non-brute techniques may not be developed that can crack it in an acceptable timeframe)
There's no cloud solution around that I am aware of that even comes close to the performance of Tianhe-IA
And note that the bottleneck for this is not going to be how quickly the attacker can work through the keyspace, it is going to be how quickly it can test each of those keys - and that'll be limited by the system you are trying to attack ... (so all the numbers above are best-case scenarios)
>It's a question of finance these days
It really isn't for the sort of numbers we are talking about. There are also power consumption limits imposed by something called the Von Neumann-Landauer Limit ...

ROFLMSO that was so much fun to read . . . I use a 13 digit alphanumeric with special characters capitals and lowercase.
I consider that to be secure enough for most instances . . . but it would not take ALL THAT long to crack if someone really wanted to . . . luckily my need for security is not great . . .

Of course, the forefront to security is not allowing someone to get to a point where they can enter your username/password to begin with.
Using my license plate wouldn't work... it's the same as my HAM radio call letters.
Just my 2¢

I'm also a ham, and I had a plate with my call letters, but I gave it up when someone broke in and stole an IC-440 HT from the glove box.
The funny thing is, while I had the plate, the validation sticker became faded. I went in for a new sticker, they said they couldn't just replace the sticker, and so they made me an entirely new plate. Your tax dollars at rest.
