代码如下: importjava.security.SecureRandom;importjava.util.Random;publicclassPasswordGenerator{privatestaticfinalintPASSWORD_LENGTH=8;privatestaticfinalStringLOWER_CASE_CHARACTERS="abcdefghijklmnopqrstuvwxyz";privatestaticfinalStringUPPER_CASE_CHARACTERS="ABCDEFGHIJKLMNOPQRSTUVWXYZ";privatestaticfinalStringNUMBERS="01...
int position = random.nextInt(charCategory.length()); password.append(charCategory.charAt(position)); } return new String(password); } } 这是一个用法示例, PasswordGenerator passwordGenerator = new PasswordGenerator.PasswordGeneratorBuilder() .useDigits(true) .useLower(true) .useUpper(true) .buil...

6、完整示例代码： 下面是一个完整的示例代码，用于生成安全且随机的密码：import java.security.SecureRandom;public class PasswordGenerator { public static void main(String[] args) { SecureRandom random = new SecureRandom(); String uppercaseLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; String lowerc...
public class RandomPasswordGenerator { private static final String UPPER_CASE = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; private static final String LOWER_CASE = UPPER_CASE.toLowerCase(); private static final String NUMBERS = "0123456789"; private static final String SPECIAL_CHARACTERS = "!@#$%^&*()...

在JCA中,对于非对称密钥,公钥使用PublicKey表示,私钥使用PrivateKey表示,若要生成一个新的公私钥对,可使用KeyPairGenerator,如下: //生成新的公私钥对 public static void genKeyPair() { KeyPairGenerator keyPairGen = KeyPairGenerator.getInstance("RSA"); keyPairGen.initialize(2048); KeyPair keyPair = ke...
上面的代码定义了一个PasswordGenerator类,其中包括了密码长度和字符集两个属性,并提供了相应的构造方法和Getter/Setter方法。 步骤2:生成密码列表 接下来,我们需要生成密码列表。密码列表可以通过遍历字符集并组合生成所有可能的密码。 publicclassPasswordGenerator{// ...publicList<String>generatePasswords(){List<Strin...
