我試圖在 Java 中導入 SecureRamdom 但是import java.security.SecureRandom;不工作。我在 Eclipse 中使用 Java SE 8。有誰知道如何導入它？

當然，這是可能的。請看下面的代碼：
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.util.Arrays;
import java.util.logging.Level;
import java.util.logging.Logger;
/**

public class SecureRandomExample {
public static void main(String[] args) {
try {
// obtain a strong SecureRandom implementation from securerandom.strongAlgorithms property of java.security.Security
// class
SecureRandom secureRandom = SecureRandom.getInstanceStrong();
// print the provided and algorithm obtained for this secureRandom
System.out.println("" + secureRandom.getProvider() + "\n" + secureRandom.getAlgorithm());
//generate 16-long seed bytes
//generate a given number of seed bytes (to seed other random number generators, for example):
byte[] bytes = secureRandom.generateSeed(16);
//print obtained bytes as string from array
System.out.println(Arrays.toString(bytes));
//to get random bytes, a caller simply passes an array of any length, which is then filled with random bytes:
secureRandom.nextBytes(bytes);
//print obtained bytes as string from array
System.out.println(Arrays.toString(bytes));
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(SecureRandomExample.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
