This project is a Java Console Application to generate Random passwords and performing a password strength check.
Functionalities:
1- Generating a Password:
- The user must answer by Yes or No the questions to know if he desires to use Uppercase/Lowercase letters, Numbers or Symbols
- The user then enters the desired length of the password
- A password alphabet is generated according to the Yes/No answers it is a String that contains the choices of the user
- Depending on the length random characters from the password alphabet are selected and put back to back to form a totally random string according to the user's needs
- The randomly generated password is then displayed on the console
2- Checking a Password's Strength:
The Strength check is based on the following criteria:
- The password uses Uppercase Letters
- The password uses Lowercase Letters
- The password uses Numbers
- The password uses Symbols
- The length of the password is 8 or more (8 is often the minimum required length for a decent password)
- The length of the password is 16 or more (16 is considered to be the minimum length for good password)
These are used to calculate a score for the password used to know what message to display to the user weak/medium/good/great password
3- Displaying Useful Information:
This is a minor feature that displays on the console so information for the user about password security (Avoid using the same password twice/ Avoid character repetition, keyboard patterns, dictionary words, letter or number sequences, etc.)
