帕赛 − 概述
Passay是一个基于Java的密码生成和验证库。它提供了全面的功能列表,以便验证/生成密码,并且高度可配置。
帕赛组件
Passay API 有 3 个核心组件。
-
规则 - 定义密码策略规则集的一个或多个规则。
-
PasswordValidator− 根据给定规则集验证密码的验证器组件。
-
PasswordGenerator− 生成密码以满足给定规则集的生成器组件。
规则概述
规则是密码验证和生成的基础块。规则分为两大类:
-
正匹配要求密码满足规则。
-
负匹配拒绝满足规则的密码。
特征
以下是 Passay 库提供的一些功能。
-
密码验证Passay 库通过根据可配置的规则集验证密码来帮助实施密码策略。它为常见用例提供了一组丰富的现有规则。对于其他情况,它提供了一个简单的规则接口来实现自定义规则。
-
密码生成 - 它提供了一个可配置的规则集,也可用于生成密码。
-
命令行工具− 它提供了自动执行密码策略的工具。
-
方便 - 易于使用。
-
可扩展 - 所有 Passay 组件都是可扩展的。
-
支持内部化 - Passay组件已准备好国际化。
帕赛 − 环境设置
设置爪哇
如果您仍然愿意为 Java 编程语言设置环境,那么本节将指导您如何在计算机上下载和设置 Java。请按照下面提到的步骤设置环境。
Java SE可从下载Java链接免费获得。因此,您可以下载基于操作系统的版本。
按照说明下载 Java 并运行 .exe以在您的计算机上安装 Java。在计算机上安装 Java 后,您需要设置环境变量以指向正确的安装目录 -
设置 Windows 2000/XP 的路径
我们假设您已经在c:\Program Files\java\jdk目录中安装了 Java −
-
右键单击“我的电脑”,然后选择“属性”。
-
单击“高级”选项卡下的“环境变量”按钮。
-
现在,更改“Path”变量,使其也包含 Java 可执行文件的路径。例如,如果路径当前设置为“C:\WINDOWS\SYSTEM32”,则将路径更改为“C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin”。
设置 Windows 95/98/ME 的路径
我们假设您已经在c:\Program Files\java\jdk目录中安装了 Java −
-
编辑“C:\autoexec.bat”文件,并在末尾添加以下行 − 'SET PATH=%PATH%;C:\Program Files\java\jdk\bin'
为 Linux、UNIX、Solaris、FreeBSD 设置路径
环境变量 PATH 应设置为指向安装 Java 二进制文件的位置。如果您在执行此操作时遇到问题,请参阅您的 shell 文档。
例如,如果您使用 bash 作为 shell,那么您可以在“.bashrc: export PATH=/path/to/java:$PATH”的末尾添加以下行
流行的 Java 编辑器
要编写 Java 程序,您需要一个文本编辑器。市场上有许多复杂的IDE。但是现在,您可以考虑以下之一 -
-
记事本 - 在Windows机器上,您可以使用任何简单的文本编辑器,如记事本(推荐用于本教程),文本板。
-
Netbeans - 它是一个开源且免费的Java IDE,可以从Welcome to Apache NetBeans 下载。
-
Eclipse− 它也是由 eclipse 开源社区开发的 Java IDE,可以从The Community for Open Innovation and Collaboration | The Eclipse Foundation 下载。
下载帕赛档案
从Maven存储库下载最新版本的Passay jar文件。在本教程中,passay-1.6.1.jar 被下载并复制到 C:\> passay 文件夹中。
操作系统 | 存档名称 |
---|---|
窗户 | 帕赛-1.6.1.jar |
Linux目录 | 帕赛-1.6.1.jar |
苹果电脑 | 帕赛-1.6.1.jar |
设置帕赛环境
将PASSAY环境变量设置为指向计算机上存储 Passay jar 的基目录位置。假设我们已经在各种操作系统上的Passay文件夹中提取了passay-1.6.1.jar,如下所示。
操作系统 | 输出 |
---|---|
窗户 | 将环境变量 PASSAY 设置为 C:\Passay |
Linux目录 | 导出PASSAY=/usr/local/Passay |
苹果电脑 | 导出 PASSAY=/Library/Passay |
设置类路径变量
将CLASSPATH环境变量设置为指向 Passay jar 位置。假设您已将passay-1.6.1.jar存储在各种操作系统上的Passay文件夹中,如下所示。
操作系统 | 输出 |
---|---|
窗户 | 将环境变量 CLASSPATH 设置为 %CLASSPATH%;%Passay%\passay-1.6.1.jar;.; |
Linux目录 | export CLASSPATH=$CLASSPATH:$PASSAY/passay-1.6.1.jar:. |
苹果电脑 | export CLASSPATH=$CLASSPATH:$PASSAY/passay-1.6.1.jar:. |
帕赛 - 密码验证
典型的密码策略包含一组规则,用于检查密码是否符合组织规则。请考虑以下策略:
-
密码长度应在 8 到 16 个字符之间。
-

例
以下示例显示了使用 Passay 库根据上述策略验证密码。
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)); } } }
输出
