If you need a C# helper function to check for strong passwords, don't forget to also read this post.1 “Americans and Cybersecurity.” Pew Research Center, Washington, D.C. ![]() If you want to use the alternative implementation, just rename the CryptoRandom2.cs file and class to CryptoRandom, replacing the previous one - or just instantiate a CryptoRandom2 object in the PasswordGenerator.cs file. In the GitHub project you'll also find an alternative CryptoRandom implementation ( CryptoRandom2), which has been taken from here (credits to Stephen Toub, Shawn Farkas and Markus Olsson). The CryptoRandom class has been taken from IdentityModel. NET Framework, replacing its standard (non-secure) behaviour with a cryptographic random number generator. The password randomness is calculated using a CryptoRandom class that mimics the standard Random class in the. That's it for now: hope you'll like it! Security considerations The default is 5 words, while I personally use 8 words for my keepassx password. By adding more words, a password will be more difficult to break. ![]() The script only has one argument, -n (or -num), which is the number of words to generate. UPDATE: as of July 2018, the PasswordOptions native support has been removed to avoid the required dependency to the class: now the class has standard parameters (two int, four boolean) having the same name of the corresponding PasswordOptions properties. To use, simply type python password.py or python password.py -n 8. Add ASP.NET Identity support services. ![]() In the likely case you have it in your ASP.NET Core project, you can use the exact same object used in the ConfigureService method of the Startup class when defining the password requirements: UsageĪs you can see by looking at the source code, the class takes a PasswordOptions object as parameter, which is shipped by the assembly, but you can easily replace it with a two int - four bool parameter group or POCO class if you don't have that package installed. The random password generated against the Mads function could have them or not, depending on the randomness: that simply won't do in my scenario, since I had to deal with the UserManager.CreateUserAsync(username, password) method of the namespace, which utterly crashes whenever the password isn't strong enough.Įventually, I ended up coding my own helper class - just like Mads Kristensen more than 11 years ago. However, the function I found in that post didn't help me much, because it had no way to ensure any strong-password requisite other than the minimum required length: more specifically, I need to generate password with at least one uppercase & lowercase letter, digit and non-alphanumeric character - and also a certain amount of unique characters. I stumbled upon this 2006 post from Mads Kristensen, which is a guy I seriously love for all the great work he did with some incredibly useful Visual Studio extensions such as Web Essentials, Web Compiler, ASP.NET Core Web Templates - and a bunch of other great stuff. Before committing into it I spent some minutes surfing the web, trying to find something I could use. Some time ago I had to implement a C# method that creates a random generated password in C#. A simple C# helper class for ASP.NET Core to generate a random password with custom strength requirements: min length, uppercase, lowercase, digits & more Introduction ![]()
