Password Strength Checker using Java

By Yash Singh

This is a project on password validator and strength checker using Java which tells the strength of our given password.

Hello folks,

Here I have created an interesting project which is used by many websites which have login credentials. This project is on Java password strength checker which checks the strength of our given password using certain conditions like password has minimum length of 8 characters, has one uppercase character, has one numeric character, etc. 

In this project I had checked eight conditions which defines the strength of our password. These conditions are as follows-

1. Password has minimum 8 characters

2. Password has maximum 16 characters

3. Password has atleast one lowercase character

4. Password has atleast one uppercase character

5. Password has atleast one numeric character

6. Password has atleast one special character

7. Password has no more than two consecutive uppercase or lowercase character

8. Password has no more than two consecutive number

If the password has all these combinations, then it is generally considered to be a strong password. If the password contains many of them, then it might be of medium strength. If it contains very few combinations then it is considered to be a weak password. And if, password does not satisfy any condition or satisfy only one condition then the password is invalid.

So that is all about my project, I hope it will help you all.
