Strong Password
|
| Expression |
^(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){1,})(?!.*\s).{7,30}$ |
| Description |
The basic expression requires at least 1 lower case, 1 upper case, 1 numeric, 1 non-word and no whitespace.
<br /><br />
The format of the expression lends itself to being parameterised, thus in C# I have a method that returns a modified pattern based on passed in parameters e.g.
<br /><br />return "^(?=(.*[a-z]){" + minLowerCase.ToString() + ",})"<br /> + "(?=(.*[\d]){" + minNumeric.ToString() + ",})"<br /> ... <br /> + ".{" + minLength.ToString() + "," + maxLength.ToString() + "}$");<br /><br />Its then possible to set the password strength via configuration files which require strong passwords in production environments, but allow weaker passwords in development environments. |

Strong Password Validation
|
| Expression |
^(?=.*[!@#$%^&*()\-_=+`~\[\]{}?|])(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).{8,20}$ |
| Description |
This should require all of the following: An uppercase letter, a lowercase letter, a number and a special character from the provided list. Lastly, it needs to be between 8 and 20 characters long.
A lot of expressions I've found here don't require all four, this should. I'm pretty new at regex though, so I hope that other people will help strengthen this expression.
When testing on this site, make sure you have the Case Insensitive checkbox turned off. |
