Question 1

How do I integrate DBZxcvbn in a Swift project?

Accepted Answer

You'll need to use Objective-C bridging by adding the library to your project and creating a bridging header. Check Apple's documentation on mixing Swift and Objective-C for steps, as DBZxcvbn is not natively Swift.

Question 2

Is DBZxcvbn better than iOS's built-in password rules?

Accepted Answer

Yes, DBZxcvbn provides more realistic strength estimation through pattern matching and entropy calculations, whereas iOS rules are simpler and less accurate for complex passwords, as highlighted in the project's philosophy.

Question 3

Can I use DBZxcvbn for server-side password validation?

Accepted Answer

No, DBZxcvbn is designed for iOS clients; for server-side, consider the original JavaScript or Python ports of zxcvbn, which are mentioned in the README as alternatives.

Question 4

How accurate is the crack time estimation in DBZxcvbn?

Accepted Answer

It uses conservative entropy calculations based on common patterns and dictionaries, making it reasonably accurate for real-world scenarios, as detailed in the Dropbox tech blog linked in the README.

Question 5

DBZxcvbn vs other iOS password libraries: which one should I choose?

Accepted Answer

Choose DBZxcvbn if you need pattern-based estimation and easy UI integration with DBPasswordStrengthMeter; for lighter, rule-based systems, simpler libraries might be sufficient without the overhead.

Question 6

How to add custom words to the dictionary in DBZxcvbn?

Accepted Answer

Use the userInputs parameter in the passwordStrength:userInputs: method to pass an array of strings, such as site-specific vocabulary, which DBZxcvbn will add to its internal dictionary for penalization.
