Random Password Generator:
Assuming each password character is chosen from a pallet of 72 possible characters, then each time one adds a character to one's password, one makes it 72 times more difficult to break. Thus, a 15 character password is 72^7 times as hard to break as an 8 character password. That's 10,000,000,000,000 times harder to break.
That is why a 15-character password composed only of random letters and numbers (a-z0-9) is about 33,000 times stronger than an 8-character password composed of characters from the entire keyboard.
How They Are Generated:
We have previously not provided full details of how we do things in hopes of preventing Reverse engineering with what we were doing... but not any more! (as of July 2011)
Here is what we will share - these are things that any competent developer should be able to accomplish. The real trick is in the exact procedures that the follow processes take place.
First we generate a string that is composed of the allowed characters. We than pad the string to ensure we have enough data to work with.
Secondly we do some basic randomizing of the allowed characters (the string) to produce a viable seed with which to work with. All grunt-work-stuff on our end. While doing so we use throw in some additional unique randomization in order to produce a nice and healthy seed.
Thirdly we take our randomized numbers and srand them just for the fun of it and a mt_rand because it is so fun to do!
Fourthly we take the above "randomized number" -> "rand numbers" and seed it with the characters allowed within each section below. (i.e.: a-z, a-z0-9, a-z + 0-9 + A-Z + Symbols, a-z + 0-9 + A-Z + Symbols + Space + ANSI)
Next we run the string through a single character duplication method that attempts to resolve any two characters next to each other from no longer being duplicate characters. For instance "3ertt5z" could become "3ertp5z", fixing the duplicate "tt" character duplication issue. Nasty password problem that haunts a lot of password generators. Thanks to @ericcoleman for assisting with this issue.
Next we validate that the strings are the right length. (i.e.: 6-chars, 15-chars, 32-char, 124-chars) Exciting Huh!
Lastly we validate that none of the strings contain any random characters not allowed within the given section to be passed along. (a menial task that we do just for you!)
The true power of our system is how our random generator process and generates the seed. That we are not willing to share. (copy cat websites annoy us)
Passwords Strengths:
We start by displaying some pretty worthless passwords (easily broken by a brute force attack), then move onto some more pretty worthless passwords, and work our way into more and more secure passwords. It is safe to say that the "probably unbreakable" passwords are just that... unbreakable -- even with most modern super computers. Of course, we do not place any warranty that they c/would not be... but it is highly unlikely that they could be. Of course, one has to ask, "how in the world could a person be expected to remember any of the 'probably unbreakable' passwords?" -- to which we do not have an answer. Obviously writing them down greatly increases the risk that somebody might find it and try it. Use at your own risk ;)
All that said, remember that if you are not a big-fan of passwords (such as ourselves), there is such a thing as a Passphrase -- which many people consider to be much more secure then a password!
If one takes into consideration a modern chipset and a budget of $1 billion (100 million custom coded encryption CPU engines in parallel), with some of the most efficient brute-force systems available, it is possible to crack a 128 bit encrypted volume in only 1,000 billion years. Of course the important part to remember here is that if the encryption key is either derived from a password, or is encrypted by a hash of a password, then $12M worth of equipment should be able to crack it in about 3 hours and $1B of equipment should crack it in about 2 minutes or so.
What is key to all of this is that cracking encryption methods is not always about using brute force against keys, but rather that guessing passwords which are derived by weak password generators are much more important to realize and use. How one generates keys and what one does to protect their keys is the crucial step to any level of security. It really does not matter if a key length takes a billion years to crack if the process of guessing the password itself only takes a few hours because they are not generated correctly!
A Word Of Caution:
Obviously we are taking security seriously with our passwords (even for the weak/worthless ones) but you should not use ANY of the basic passwords that are lower in security then our "Secure" level for MS Window passwords or for WEP/WPA keys. The reason for this is that some very popular and easy to use tools already exist to acquire these with very little effort. Better yet, disable your Wifi all together!
This is especially true for MS Windows user-account passwords, because any that are UNDER 14-characters can be cracked with almost no effort at all, regardless of the version of Windows, so it is best to use passwords/passphrases that are greater then 14-characters in length for your Windows Users Account Password.
As for how long and strong you should use for WEP/WPA Keys, it is our belief that unless you are running a Cisco wireless network, or third-party software, wireless security is non-existent, regardless of how long or strong of a password/passphrase you use. Simply put, there are just too many software programs out there that are able to sniff or force wireless passwords. Your best solution is to either disable wireless or go with an option that provides wireless security outside the boundaries of WEP/WPA.
Updates & Changes:
February 03, 2012 -- We have resolved a random occurance of the "True GUID" from periodically being one character short. We fixed that and added a length verification indicator after the GUID. Correct character length for a True GUID is 36 characters.
July 17, 2011 -- We have added an additional layer of randomization to the following options (which has added an additional 2.75 x 10131 worth of randomization): Secure, Relatively Secure, Highly Secure, Extremely Secure. This has been applied to the initial seed.
July 07, 2011 -- We have added a new section that generates GUID / UUID results if you need quick access to one.
July 06, 2011 -- Thanks to @ericcoleman we have added some code to help reduce (eliminate?) two identical characters from displaying right after each other. We have also switched to utilize a new random generator that we have developed that greatly decreases our duplication factor. We have tested our random generator (for passwords of 32-chars in length) at one billion rows without a duplication! We have renamed "Very Secure" to "Relatively Secure" so that we could introduce a 32-char string, which we are now calling "Very Secure". It is, for the most part identical to doing a md5() except it is generated via our random password generator and checked for identical-next-character-duplications. We have also relocated to the www.RandomPasswords.Net domain!
June 03, 2011 -- We resolved an issue with the 128-char "Highly Useful" passwords today, that was pointed out to us by a California County employee, that resulted in the vast majority of the passwords being all lowercase. We took the opportunity to apply much greater randomization seeds to this set of passwords while we were working on it.
6/16/2010 -- We resolved a small issue with the "Completely Worthless", "Worthless" and "Weak" passwords that was pointed out to us by a school employee. We did not think people would actually use them so we never double-checked them for duplication cycles. Oops.
10/19/2009 -- We added the "Highly Useful: (128-chars in length, including: a-z + 0-9 + A-Z)" set today. We should have no real security value as it is just a randomized 128-character string with no security checking for things such as consistent character checking, which is important in alpha-numeric only strings. This is more to just give those of you needing 128-character strings a quick way to have some.
9/6/2009 -- We added the "Almost Unbreakable: (255-chars in length, including: a-z + 0-9 + A-Z + Symbols + Space + ANSI)" set today due to request from a developer that uses (max) 255-character passwords.
3/8/2009 -- We added two more sets of passwords today. The "Unrealistically Unbreakable" a huge 512-character string and our first "Dare-We-Say Unbreakable?" password, with a massively insane 1024-characters in length! Note that both of these use [space] and it does NOT strip the [space] if the [space] occurs at the end of the password - by design. These two additional sizes where added due to requests we have received for even long passwords than our previously 124-character passwords! Because of the size and time it takes to produce these longer passwords, we are only displaying two of them at any given time.
9/14/2008 -- We added two more sets of passwords today. The "Extremely Secure" and "Probably Unbreakable", both 64-character passwords in length. Note that the "Probably Unbreakable" DOES use [space] and it does NOT strip the [space] if the [space] occurs at the end of the password, by design. The 64-character password is a popular length by many hard drive volume cryptograph programs (including TrueCrypt) and we've gotten a number of requests to add this length.
Updated: 7/7/2008 -- We made three changes to the "probably unbreakable" level passwords today.
- Added: - We now generate a password that is three times longer then necessary, then generate a randomized start/end point and from there, "splice out" a 128-character password. This extra level of randomization will further increase the "true randomness" of this process. Rather then our software always using a specific start/end point, by generating this extra large password and then randomly splitting out a section of the extra large password, it will make it that much more unlikely to have problems with duplication factors. It is beyond our math abilities to compute what increase of to-the-nth-power of randomness this gives us, so that is saying something.
- Updated: - We have also increased the included characters by an additional 20 characters.
- Updated: - We have also made it so a random character will replace the first and/or last character if it was generated as a [space] to help reduce copy/paste errors.
Updated: 2/3/2008 -- Decided to add another step of randomization for all generated passwords that are "Fairly Strong" and above.
- Added: - We now randomize the "available characters" (i.e.: a-z, a-z0-9, a-z + 0-9 + A-Z + Symbols, etc) rather then using a set-pattern. We should have done this from the start, but neglected to do so. This extra step should truly make the "probably unbreakable" unbreakable to most modern non-super-computers! Unsure of the bit-level increase on this (and unwilling to share further details of what we have done to protect our methodology), but it is a huge increase to the overall bit-level!
