Java 如何在从base64解码后返回锁定的密钥库实例？

我正在编写与密钥库和证书相关的JAVA项目。我写了一个方法来；提供证书集时生成动态密钥库，将密钥库编码为Base64编码字符串，将Base64字符串解码为PKCS12密钥库实例。 在生成密钥库时，我为它提供一个密码，如下所示

Security.addProvider(new BouncyCastleProvider());

KeyStore keystore = KeyStore.getInstance("PKCS12");
keystore.load(null, null);

keystore.setCertificateEntry(aliasName1, certificate1);
keystore.setCertificateEntry(aliasName2, certificate2);

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
char[] keystorePasswordAsCharArray = keystorePassword.toCharArray();

OutputStream outputStreamForEncode = Base64.getEncoder().wrap(byteArrayOutputStream);
keystore.store(outputStreamForEncode, keystorePasswordAsCharArray); 
.
.
.

KeyStore outputKeystore = KeyStore.getInstance("PKCS12");

InputStream inputStream = new ByteArrayInputStream(base64EncodedKeystoreString.getBytes());
InputStream inputStreamForDecode = Base64.getDecoder().wrap(inputStream);

char[] keystorePasswordAsCharArray = keystorePassword.toCharArray();
outputKeystore.load(inputStreamForDecode, keystorePasswordAsCharArray);

在那之后，当解码时，我也提供一个密码给它，如下所示

Security.addProvider(new BouncyCastleProvider());

KeyStore keystore = KeyStore.getInstance("PKCS12");
keystore.load(null, null);

keystore.setCertificateEntry(aliasName1, certificate1);
keystore.setCertificateEntry(aliasName2, certificate2);

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
char[] keystorePasswordAsCharArray = keystorePassword.toCharArray();

OutputStream outputStreamForEncode = Base64.getEncoder().wrap(byteArrayOutputStream);
keystore.store(outputStreamForEncode, keystorePasswordAsCharArray); 
.
.
.

KeyStore outputKeystore = KeyStore.getInstance("PKCS12");

InputStream inputStream = new ByteArrayInputStream(base64EncodedKeystoreString.getBytes());
InputStream inputStreamForDecode = Base64.getDecoder().wrap(inputStream);

char[] keystorePasswordAsCharArray = keystorePassword.toCharArray();
outputKeystore.load(inputStreamForDecode, keystorePasswordAsCharArray);

然后输出密钥库实例被解锁，我从方法返回实例

但是我想返回锁定的密钥库实例。我该怎么做
