Generated password does not meet the requirements

[ewefie]

I've spotted an issue while generating passwords with following code:

`var faker = new Faker();

var password = faker.internet().password(8, 100, true, true, true); //(minLength, max Length, includeUppercase, includeSpecial, includeDigit)`

The generated password does not always include a digit (about 1-2% results are incorrect).

Sample incorrect output:

• ^Ez!Wdi@
• *Wow$&pIkeK@*OF ("O" in this one is not a zero)

Faker Version: 1.0.2

I have the same problem, we are trying to fix it.

I have analyzed the source code, and in my opinion, the generated password is too random, there is a pretty big chance of overwriting generated digits with special characters. In my project, I managed it by checking if the generated password meets my expectations before I use it.

private static String generateStrongPassword() {
var password = new Faker().internet().password(8, 16, true, false, true);
if (isPasswordValid(password)) {
return password;
}
return generateStrongPassword();
}

private static boolean isPasswordValid(String password) {
return nonNull(password) && password.length() >= 8 &&
password.chars().anyMatch(Character::isDigit) &&
password.chars().anyMatch(Character::isLowerCase) &&
password.chars().anyMatch(Character::isUpperCase);
}

This is a right solution. But in my opinion, I try to modify some source code to kill this problem.

Also, when I read the source code, another bug happens. In src/test/java/com.github.javafaker/InternetTest. Its method "testPasswordMinLengthMaxLengthIncludeUpperCaseIncludeSpecialIncludeDigit()" tests the digit with
assertThat(faker.internet().password(10, 25, true, true, true), matchesRegularExpression("[a-zA-Z\d!@#$%^&*]{10,25}"));
But actually I find the "\d" is useless, it means the digit test is useless, so "^*Wow$&pIkeK@*OF" is PASS, and "aaaaaaaaaaaA@" is also PASS.
This is also a bug, if I have enough time, I will try this.
