Below are some rules that can be used for creating a strong password: This largely involves constructing a strong password, but includes other aspects such as changing a password periodically, as well as being aware of, and avoiding the use of common passwords (password, 123456, qwert.). How to create a secure passwordĬreating a secure password can be achieved by following certain rules that are designed to increase password security. This includes controls such as two-step authentication for your password, or locking the account for a period of time after a given number of failed attempts. Security controls include safeguards that are in place to detect, avoid, or minimize security risks. For example, if a password involves a person's name, birthday, or other personal information that typically would not be very difficult to find out, the password would likely make for a weak password.Īside from the actual password, proper security controls play a significant role in reducing the risk of a security breach. This is affected by the length, complexity, and unpredictability of the password. Although it varies, usually, password strength is an estimate of how many trials would be required on average for someone to successfully guess the password. Password strength is a measure of how effective a password is against being guessed or against brute-force attacks. As such, it is important to understand how to construct a strong password (or use a password generator) as well as to understand how to take measures to safeguard the password. In today's Internet age, it is likely that most people have experience with having a password for some kind of account. A password is typically a string of characters that may include letters, numbers, and symbols that can be used to access something, typically an account, and prevent others from accessing it. It's something that I've always intended to write but have never quite got round to. The easiest approach - and I suspect the one used by most crossword generators - would be to provide a number of pre-prepared templates, have the user pick one and then go and populate it but it would be a rather fun exercise to to come up with a generator that provided grids according to a selected difficulty level and min/max word length parameters but with some degree of randomness to ensure that it doesn't keep churning out the same pattern each time the same values are provided. Some grid formats are inherently harder for the solver than others - a white square at 0,0 will make life easier for the solver than one with a black square at 0,0, for instance and the more mutually checking letters that there are, the easier it will be to solve. This poses a few interesting challenges, if trying to create from scratch with some degree of randomisation - there must be a minimum word length of 3 along with a good mix of word lengths along with a desirable range of ratios of black to white squares. In order to achieve that, it's pretty much essential to start with the a fully-defined grid. Then, when we actually place the word, we call:Ĭonventionally, a standard crossword has a 15x15 square 180 o symmetrical grid. Return result = word.Length ? -1 : result Int xStar = x - _dirX, yStar = y - _dirY Int CanBePlaced( string word, int x, int y, int dir) The demo source code was created using C# and Visual Studio 2010.įirst, for each word about to be placed, we check if this place is valid: The file should be an ASCII one, with one word per line.
Loading words from a file, or placing them manually.
An optimization process, used to find the optimal arrangement of any given set of words, which leave a minimum number of black square.
Two words placed horizontally or vertically one after the other will have at least one black square separating between the two.
Minimal distance between words placed at the same dimension.
Latin words are placed left to right, and from top to bottom. To comply with this requirement, words in such language go from right to left, when placed horizontally, and still, from top to bottom when placed vertically.
Supporting right-to-left languages, such as Hebrew.
While designing this application, there were several guidelines to comply with: The application described and included in this article is useful whenever there is a need to create a mechanism which will place words as a crossword, which would be the first step before composing clues and questions in which their answers will form these words. A crossword is a word puzzle created from a grid of white and black squares, placing words horizontally and vertically on these squares while each two words which cross each other require having an identical letter at the place they are crossed.
