java - 无法更改 keystore 格式

Question

我正在尝试使用来自最新 JRE(版本 1.8.0_151)的 keytool 创建一些 keystore 。当我使用此命令创建 keystore 时 keytool -genkey -alias serverprivate -keystore server.private -keyalg rsa -storepass apassword -keypass apassword 它向我显示此警告:

Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate 
to  PKCS12 which is an industry standard format using "keytool 
-importkeystore -srckeystore server.private -destkeystore server.private
-deststoretype pkcs12".

所以我输入了命令，它说完成了，旧的 keystore 被保存在 server.private_old 中。但是当我运行 keytool -list -keystore server.private 并输入密码时，它仍然列为 JKS 而不是 PKCS12。这是为什么？

更新
它也没有悄悄地更改为 pkcs12，因为当我在 Java 中使用 KeyStore store = KeyStore.getInstance("pkcs12"); 时它会抛出一个错误，而在使用 getInstance("JKS");

更新 2
当使用 keytool -genkey -alias serverprivate -keystore server.private -storetype PKCS12 -keyalg rsa 时，它没有向我显示警告，但在使用 keytool 时仍显示为 JKS keystore -列出 server.private。

Answer 1

这似乎是 keytool 显示的错误，而不是它的作用。考虑以下实验。

(编辑:bug report filed)

首先我的jdk版本是1.8.0_152:

excalibur:~ ronan$ java -version
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)

现在，按照您指定的方式创建 keystore :

excalibur:~ ronan$ keytool -genkey -alias serverprivate -keystore server.private -keyalg rsa -storepass apassword -keypass apassword
What is your first and last name?
  [Unknown]:  Art Vandelay
What is the name of your organizational unit?
  [Unknown]:  Export/Import
What is the name of your organization?
  [Unknown]:  Vandelay Industries
What is the name of your City or Locality?
  [Unknown]:  New York
What is the name of your State or Province?
  [Unknown]:  New York
What is the two-letter country code for this unit?
  [Unknown]:  US
Is CN=Art Vandelay, OU=Export/Import, O=Vandelay Industries, L=New York, ST=New York, C=US correct?
  [no]:  yes


Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore server.private -destkeystore server.private -deststoretype pkcs12".

现在，按照给出的说明进行操作:

excalibur:~ ronan$ keytool -importkeystore -srckeystore server.private -destkeystore server.private -deststoretype pkcs12
Enter source keystore password:  
Entry for alias serverprivate successfully imported.
Import command completed:  1 entries successfully imported, 0 entries failed or cancelled

Warning:
Migrated "server.private" to Non JKS/JCEKS. The JKS keystore is backed up as "server.private.old".

但是当我们用 keytool 列出它时，它仍然显示 JKS。

excalibur:~ ronan$ keytool -list -keystore server.private
Enter keystore password:  
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 1 entry

serverprivate, Dec 4, 2017, PrivateKeyEntry, 
Certificate fingerprint (SHA1): 16:E8:C6:12:7A:F1:7A:B8:64:98:EC:12:C4:07:9E:67:06:BD:DD:BD

但是，openssl 可以将其解析为 pkcs12 就好了。

excalibur:~ ronan$ openssl pkcs12 -in server.private
Enter Import Password:
MAC verified OK

下面的 Java 代码片段也可以解析它。

import java.io.FileInputStream;
import java.security.KeyStore;
import java.util.Collections;

public class Main {
    public static void main(String[] args) throws Exception {
        KeyStore pkcs12 = KeyStore.getInstance("PKCS12");
        pkcs12.load(new FileInputStream("../../../server.private"), "apassword".toCharArray());
        for (String alias : Collections.list(pkcs12.aliases())) {
            System.out.println(alias);
        }
    }
}

输出是

serverprivate
