Question

我尝试使用最新JRE（版本1.8.0_151）中的keytool创建一些密钥库。当我使用此命令keytool -genkey -alias serverprivate -keystore server.private -keyalg rsa -storepass apassword -keypass apassword创建密钥库时，它会向我显示此警告：

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".

所以我输入命令，它说完了，旧的密钥库保存在server.private_old中。但是当我运行keytool -list -keystore server.private并输入密码时，它仍然被列为JKS而不是PKCS12。这是为什么？

更新
它也没有默默地更改为pkcs12，因为当我在java中使用KeyStore store = KeyStore.getInstance("pkcs12");时会抛出错误，而在使用getInstance("JKS");时它可以正常工作

更新2
使用keytool -genkey -alias serverprivate -keystore server.private -storetype PKCS12 -keyalg rsa时，它不会向我显示警告，但在使用keytool -list server.private时仍会显示为JKS密钥库。

Answer 1

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，按照您的指定创建密钥库：

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，按照给出的指示：

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，它仍然说是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

并且以下Java代码段也可以解析它。

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

serverprivate

无法更改密钥库格式
