Passay 简明教程
Passay - Password Validation
典型的密码策略包含一系列规则，以检查密码是否符合组织规则。请考虑以下策略：
A typical Password policy contains a set of rules to check a password if is compliant with organization rules. Consider the following policy:
-
Length of password should be in between 8 to 16 characters.
-
A password should not contain any whitespace.
-
A password should contains each of the following: upper, lower, digit and a symbol.
Example
以下示例显示了使用 Passay 库根据上述策略对密码进行验证的过程。
The below example shows the validation of a password against above policy using Passay library.
import java.util.ArrayList;
import java.util.List;
import org.passay.CharacterRule;
import org.passay.EnglishCharacterData;
import org.passay.LengthRule;
import org.passay.PasswordData;
import org.passay.PasswordValidator;
import org.passay.Rule;
import org.passay.RuleResult;
import org.passay.WhitespaceRule;
public class PassayExample {
public static void main(String[] args) {
List<Rule> rules = new ArrayList<>();
//Rule 1: Password length should be in between
//8 and 16 characters
rules.add(new LengthRule(8, 16));
//Rule 2: No whitespace allowed
rules.add(new WhitespaceRule());
//Rule 3.a: At least one Upper-case character
rules.add(new CharacterRule(EnglishCharacterData.UpperCase, 1));
//Rule 3.b: At least one Lower-case character
rules.add(new CharacterRule(EnglishCharacterData.LowerCase, 1));
//Rule 3.c: At least one digit
rules.add(new CharacterRule(EnglishCharacterData.Digit, 1));
//Rule 3.d: At least one special character
rules.add(new CharacterRule(EnglishCharacterData.Special, 1));
PasswordValidator validator = new PasswordValidator(rules);
PasswordData password = new PasswordData("Microsoft@123");
RuleResult result = validator.validate(password);
if(result.isValid()){
System.out.println("Password validated.");
} else {
System.out.println("Invalid Password: " + validator.getMessages(result));
}
}
}
