无法解密使用引发的数据异常

Question

使用，我试图对一个服务帐户进行身份验证，该帐户镜像示例代码http://samples.google-api-java-client.googlecode.com/hg/storage-serviceaccount-cmdline-sample/src/main/java/com/google/api/services/samples/storage/serviceaccount/cmdline/StorageServiceAccountSample.java中概述的过程，以便使用Blogger。我已经创建了服务帐户，并下载了API仪表板提供的.p12文件。这个.p12文件作为一个资源存储在jar文件中，其中包含用于连接到Blogger服务的代码。在GoogleCredentials.Builder对象上运行GoogleCredentials.Builder时，我会遇到一个带有消息的IOException，该消息简单地表示“it”不能显示数据。下面是所讨论的代码片段(删除了文件名)和堆栈跟踪块，我认为这是相关的。关于这一例外的原因，我有点不知所措。使用openssl，我能够隔离地验证p12文件。

代码

httpTransport = GoogleNetHttpTransport.newTrustedTransport();

File p12File = File.createTempFile("filename", ".p12");
FileOutputStream p12FileOutputStream = new FileOutputStream(p12File);
IOUtils.copy(getClass().getResourceAsStream("/ACCESS-KEYS/filename.p12"), p12FileOutputStream);

p12FileOutputStream.close();

credential = new GoogleCredential.Builder().setTransport(httpTransport)
            .setJsonFactory(jsonFactory)
            .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
            .setServiceAccountScopes(Collections.singleton(BloggerScopes.BLOGGER))
            .setServiceAccountPrivateKeyFromP12File(p12File)
            .build();

堆栈跟踪

根据上面user1516873提供的响应在这里发布最后的代码。注意，这个问题与原始问题之间的相关差异是第3行，其中"SunJSSE“是显式设置的。

httpTransport = GoogleNetHttpTransport.newTrustedTransport();

KeyStore keyStore = KeyStore.getInstance("PKCS12", "SunJSSE");
keyStore.load(getClass().getResourceAsStream("/ACCESS-KEYS/filename.p12"), "notasecret".toCharArray());
        PrivateKey key = (PrivateKey) keyStore.getKey("privatekey", "notasecret".toCharArray());

credential = new GoogleCredential.Builder().setTransport(httpTransport)
                .setJsonFactory(jsonFactory)
                .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)      
                .setServiceAccountScopes(Collections.singleton(BloggerScopes.BLOGGER))
                .setServiceAccountPrivateKey(key)
                .build();
