How To Create An Uncrackable Password
For maximum security, passwords should not be cohesive words or phrases and should not be too obviously related to something like your birthday or the birthday of someone close to you. Personal information is one of the first things used when people attempt to break passwords.
This article assumes brute force is the only way to crack a password. It didn’t even consider rainbow tables. This article only talks about how to make a slightly more secure password. So instead of someone cant guess that your password is spiderman, because it’s sp1d3rman or something. Those are defiantly not uncrackable passwords. I guess it would be a useful reading for people that use common words and such for passwords.
Some web registrations won’t even allow special characters above the number keys let alone the “alt codes”. Besides, you can lock yourself out due to a different encoding setting if you use the special keys.
Some work requires these “strong” passwords. They have to have one number, one lowercase letter, one capital letter, ane one non-alpha char, and be at least 8 chars long. Also, the password needs to be changed every 30 days. So, since there is no way to remember this crap, everyone just writes their current password on a post-it note on their desks. That’s great security!
From a theoretical standpoint, a One-Time Pad should be uncrackable, however it does require the users to know which key to use at what time (and the key can only be used once and must be as long as the message). I find just using the standard password policy of: 8 characters, at least one upper, one lower, one numeral, one punctuation mark, no dictionary word, no date, no license plate works for most intents and purposes.
An even easier and arguably more effective method is to use a public-private key with a pass phrase. Pass phrases are great in that you can even use stuff like an exert from your favorite book and you should be pretty safe from brute force if it’s of any reasonable length.
No password is safe. It can only be more secure than another version, but nothing is uncrackable. A password is only as safe as the encryption and the amount of time the hacker has, and their determination to break it.
