我使用 openssl 生成密钥/证书

openssl.exe req -x509 -days 1000 -newkey rsa:1024 -keyout key.pem -out cert.pem

它提示输入密码。我猜测密码是用于密钥加密的。但是我没有指定任何密码。在这种情况下使用什么密码？

我正在尝试Java反射和内联字符串,并得出结果,我发现令人困惑.

import java.lang.reflect.Field;

public class HappyDebugging {

    public static void main(String[] args) throws Exception {
        defineTrueFalse();

        System.out.println("true is " + true); // why is it "true is true"?
        System.out.println("false is " + false);
        System.out.println(true);
        System.out.println(false);
        System.out.println("true");
        System.out.println("false");
        System.out.println("true is " + Boolean.valueOf(true));
        System.out.println("false is " + Boolean.valueOf(false));
        System.out.println("true is " + Boolean.valueOf("true"));
        System.out.println("false is " + Boolean.valueOf("false"));
    }

    static void defineTrueFalse() throws Exception{
        Field field = String.class.getDeclaredField("value");
        field.setAccessible(true);
        field.set("true", new char[] {'f', 'a', 'l', 's', 'e'});
        field.set("false", new char[] {'t', …
